-### Removed
-
-## [5.0.0] 2021-04-30
-### Added
-- A new and improved [`String` standard library](https://github.com/aeternity/aesophia/blob/master/docs/sophia_stdlib.md#string)
-  has been added. Use it by `include "String.aes"`. It includes functions for
-  turning strings into lists of characters for detailed manipulation. For
-  example:
-  ```
-  include "String.aes"
-  contract C =
-    entrypoint filter_all_a(s: string) : string =
-      String.from_list(List.filter((c : char) => c != 'a', String.to_list(s)))
-  ```
-  will return a list with all `a`'s removed.
-
-  There are also convenience functions `split`, `concat`, `to_upper`,
-  `to_lower`, etc.
-
-  All String functions in FATEv2 operate on unicode code points.
-- Operations for pairing-based cryptography has been added the operations
-  are in the standard library [BLS12_381](https://github.com/aeternity/aesophia/blob/master/docs/sophia_stdlib.md#bls12_381).
-  With these operations it is possible to do Zero Knowledge-proofs, etc.
-  The operations are for the BLS12-381 curve (as the name suggests).
-- Calls to functions in other contracts (i.e. _remote calls_) can now be
-  [`protected`](https://github.com/aeternity/aesophia/blob/master/docs/sophia.md#protected-contract-calls).
-  If a contract call fails for any reason (for instance, the remote contract
-  crashes or runs out of gas, or the entrypoint doesn't exist or has the
-  wrong type) the parent call also fails. To make it possible to recover
-  from failures, contract calls takes a named argument `protected : bool`
-  (default `false`).
-
-  If `protected = true` the result of the contract call is wrapped in an
-  `option`, and `Some(value)` indicates a succesful execution and `None`
-  indicates that the contract call failed. Note: any gas consumed until
-  the failure is still charged, but all side effects in the remote
-  contract are rolled back on failure.
-- A new chain operation [`AENS.update`](https://github.com/aeternity/aesophia/blob/master/docs/sophia.md#aens-interface)
-  is supported.
-- New chain exploring operations `AENS.lookup` and `Oracle.expiry` to
-  look up an AENS record and the expiry of an Oracle respectively, are added.
-- Transaction introspection (`Auth.tx`) has been added. When a Generalized
-  account is authorized, the authorization function needs access to the
-  transaction (and the transaction hash) for the wrapped transaction. The
-  transaction and the transaction hash is available `Auth.tx`, it is only
-  available during authentication if invoked by a normal contract call
-  it returns `None`. Example:
-  ```
-  switch(Auth.tx)
-    None      => abort("Not in Auth context")
-    Some(tx0) =>
-      switch(tx0.tx)
-        Chain.SpendTx(_, amount, _)  => amount > 400
-        Chain.ContractCallTx(_, _)   => true
-        _                            => false
-  ```
-- A debug mode is a added to the compiler. Right now its only use is to
-  turn off hermetization.
-### Changed
-- The function `Chain.block_hash(height)` is now (in FATEv2) defined for
-  the current height - this used to be an error.
-- Standard library: Sort is optimized to do `mergesort` and a `contains`
-  function is added.
-- Improved type errors and explicit errors for some syntax errors (empty code
-  blocks, etc.).
-- Compiler optimization: The ACI is generated alongside bytecode. This means
-  that multiple compiler passes can be avoided.
-- Compiler optimization: Improved parsing (less stack used when transpiled).
-- A bug where constraints were handled out of order fixed.
-- Fixed calldata decoding for singleton records.
-- Improved the documentation w.r.t. signatures, especially stressing the fact that
-  the network ID is a part of what is signed.
-### Removed
-
-## [4.3.0]
-### Added
-- Added documentation (moved from `protocol`)
-- `Frac.aes` – library for rational numbers
-- Added some more meaningful error messages
-- Exported several parsing functionalities
- - With option `keep_included` it is possible to see which files were included during the parse
- - There is a function `run_parser` that be used to evaluate any parsing rule
- - Exported parsers: `body`, `type` and `decl`
-### Changed
-- Performance improvements in the standard library
-- Fixed ACI encoder to handle `-` unary operator
-- Fixed including by absolute path
-- Fixed variant type printing in the ACI error messages
-- Fixed pretty printing of combined function clauses
-### Removed
-- `let` definitions are no longer supported in the toplevel of the contract
-- type declarations are no longer supported
-
-## [4.2.0] - 2020-01-15
-### Added
-- Allow separate entrypoint/function type signature and definition, and pattern
-  matching in left-hand sides:
-  ```
-    function
-      length : list('a) => int
-      length([])      = 0
-      length(x :: xs) = 1 + length(xs)
-  ```
-- Allow pattern matching in list comprehension generators (filtering out match
-  failures):
-  ```
-    function somes(xs : list(option('a))) : list('a) =
-      [ x | Some(x) <- xs ]
-  ```
-- Allow pattern matching in let-bindings (aborting on match failures):
-  ```
-    function test(m : map(int, int)) =
-        let Some(x) = Map.lookup(m, 0)
-        x
-  ```
-### Changed
-- FATE code generator improvements.
-- Bug fix: Handle qualified constructors in patterns.
-- Bug fix: Allow switching also on negative numbers.
-### Removed
-
-## [4.1.0] - 2019-11-26
-### Added
-- Support encoding and decoding bit fields in call arguments and results.
-### Changed
-- Various improvements to FATE code generator.
-### Removed
-
-## [4.0.0] - 2019-10-11
-### Added
-- `Address.to_contract` - casts an address to a (any) contract type.
-- Pragma to check compiler version, e.g. `@compiler >= 4.0`.
-- Handle numeric escapes, i.e. `"\x19Ethereum Signed Message:\n"`, and similar strings.
-- `Bytes.concat` and `Bytes.split` are added to be able to
-  (de-)construct byte arrays.
-- `[a..b]` language construct, returning the list of numbers between
-  `a` and `b` (inclusive). Returns the empty list if `a` > `b`.
-- [Standard libraries](https://github.com/aeternity/aesophia/blob/master/docs/sophia_stdlib.md)
-- Checks that `init` is not called from other functions.
-- FATE backend - the compiler is able to produce VM code for both `AEVM` and `FATE`. Many
-  of the APIs now take `{backend, aevm | fate}` to decide wich backend to produce artifacts
-  for.
-- New builtin functions `Crypto.ecrecover_secp256k1: (hash, bytes(65)) => option(bytes(20))`
-  and `Crypto.ecverify_secp256k1 : (hash, bytes(20), bytes(65)) => bool` for recovering
-  and verifying an Ethereum address for a message hash and a signature.
-- Sophia supports list comprehensions known from languages like Python, Haskell or Erlang.
-  Example syntax:
-```
-[x + y | x <- [1,2,3,4,5], let k = x*x, if (k > 5), y <- [k, k+1, k+2]]
-// yields [12,13,14,20,21,22,30,31,32]
-```
-- A new contract, and endpoint, modifier `payable` is introduced. Contracts, and enpoints,
-  that shall be able to receive funds should be marked as payable. `Address.is_payable(a)`
-  can be used to check if an (contract) address is payable or not.
-### Changed
-- Nice type error if contract function is called as from a namespace.
-- Fail on function definitions in contracts other than the main contract.
-- Bug fix in variable optimization - don't discard writes to the store/state.
-- Bug fixes in error reporting.
-- Bug fix in variable liveness analysis for FATE.
-- Error messages are changed into a uniform format, and more helpful
-  messages have been added.
-- `Crypto.<hash_fun>` and `String.<hash_fun>` for byte arrays now only
-  hash the actual byte array - not the internal ABI format.
-- More strict checks for polymorphic oracles and higher order oracles
-  and entrypoints.
-- `AENS.claim` is updated with a `NameFee` field - to be able to do
-  name auctions within contracts.
-- Fixed a bug in `Bytes.to_str` for AEVM.
-- New syntax for tuple types. Now 0-tuple type is encoded as `unit` instead of `()` and
-  regular tuples are encoded by interspersing inner types with `*`, for instance `int * string`.
-  Parens are not necessary. Note it only affects the types, values remain as their were before,
-  so `(1, "a") : int * string`
-- The `AENS.transfer` and `AENS.revoke` functions have been updated to take a name `string`
-  instead of a name `hash`.
-- Fixed a bug where the `AEVM` backend complained about a missing `init` function when
-  trying to generate calldata from an ACI-generated interface.
-- Compiler now returns the ABI-version in the compiler result map.
-- Renamed `Crypto.ecverify` and `Crypto.ecverify_secp256k1` into `Crypto.verify_sig` and
-  `Crypto.verify_sig_secp256k1` respectively.
-### Removed
-
-## [3.2.0] - 2019-06-28
-### Added
-- New builtin function `require : (bool, string) => ()`. Defined as
-    ```
-    function require(b, err) = if(!b) abort(err)
-    ```
-- New builtin functions
-    ```
-    Bytes.to_str : bytes(_) => string
-    Bytes.to_int : bytes(_) => int
-    ```
-  for converting a byte array to a hex string and interpreting it as a
-  big-endian encoded integer respectively.
-### Changed
-- Public contract functions must now be declared as *entrypoints*:
-  ```
-  contract Example =
-    // Exported
-    entrypoint exported_fun(x) = local_fun(x)
-    // Not exported
-    function local_fun(x) = x
-  ```
-  Functions in namespaces still use `function` (and `private function` for
-  private functions).
-- The return type of `Chain.block_hash(height)` has changed, it used to
-  be `int`, where `0` denoted an incorrect height. New return type is
-  `option(hash)`, where `None` represents an incorrect height.
-- Event name hashes now use BLAKE2b instead of Keccak256.
-- Fixed bugs when defining record types in namespaces.
-- Fixed a bug in include path handling when passing options to the compiler.
-### Removed
-
-## [3.1.0] - 2019-06-03
-### Added
-### Changed
-- Keyword `indexed` is now optional for word typed (`bool`, `int`, `address`,
-  ...) event arguments.
-- State variable pretty printing now produce `'a, 'b, ...` instead of `'1, '2, ...`.
-- ACI is restructured and improved:
-    - `state` and `event` types (if present) now appear at the top level.
-    - Namespaces and remote interfaces are no longer ignored.
-    - All type definitions are included in the interface rendering.
-    - API functions are renamed, new functions are `contract_interface`
-      and `render_aci_json`.
-- Fixed a bug in `create_calldata`/`to_sophia_value` - it can now handle negative
-  literals.
-### Removed
-
-## [3.0.0] - 2019-05-21
-### Added
-- `stateful` annotations are now properly enforced. Functions must be marked stateful
-  in order to update the state or spend tokens.
-- Primitives `Contract.creator`, `Address.is_contract`, `Address.is_oracle`,
-  `Oracle.check` and `Oracle.check_query` has been added to Sophia.
-- A byte array type `bytes(N)` has been added to generalize `hash (== bytes(32))` and
-  `signature (== bytes(64))` and allow for byte arrays of arbitrary fixed length.
-- `Crypto.ecverify_secp256k1` has been added.
-### Changed
-- Address literals (+ Oracle, Oracle query and remote contracts) have been changed
-  from `#<hex>` to address as `ak_<base58check>`, oracle `ok_<base58check>`,
-  oracle query `oq_<base58check>` and remote contract `ct_<base58check>`.
-- The compilation and typechecking of `letfun` (e.g. `let m(f, xs) = map(f, xs)`) was
-  not working properly and has been fixed.
-### Removed
-- `let rec` has been removed from the language, it has never worked.
-- The standalone CLI compiler is served in the repo `aeternity/aesophia_cli` and has
-  been completely removed from `aesophia`.
-
-## [2.1.0] - 2019-04-11
-### Added
-- Stubs (not yet wired up) for compilation to FATE
-- Add functions specific for Calldata decoding
-- Support for `Auth.tx_hash`, not available in AEVM until Fortuna release
-
-### Changed
-- Improvements to the ACI generator
-
-## [2.0.0] - 2019-03-11
-### Added
-- Add `Crypto.ecverify` to the compiler.
-- Add `Crypto.sha3`, `Crypto.blake2`, `Crypto.sha256`, `String.blake2` and
-  `String.sha256` to the compiler.
-- Add the `bits` type for working with bit fields in Sophia.
-- Add Namespaces to Sophia in order to simplify using library contracts, etc.
-- Add a missig type check on the `init` function - detects programmer errors earlier.
-- Add the ACI (Aeternity Contract Interface) generator.
-
-### Changed
-- Use native bit shift operations in builtin functions, reducing gas cost.
-- Improve type checking of `record` fields - generates more understandable error messages.
-- Improved, more coherent, error messages.
-- Simplify calldata creation - instead of passing a compiled contract, simply
-  pass a (stubbed) contract string.

-# Contributing to Sophia
-
-## Checklist For Creating New Pull Requests
-
-The following points should be considered before creating a new PR to the Sophia compiler.
-
-### Documentation
-
-- The [Changelog](CHANGELOG.md) file should be updated for all PRs.
-- If a PR introduces a new feature that is relevant to the users of the language, the [Sophia Features Documentation](docs/sophia_features.md) should be updated to describe the new feature.
-- If a PR introduces new syntax (e.g. changes in [aeso_syntax.erl](src/aeso_syntax.erl), [aeso_scan.erl](src/aeso_scan.erl), or [aeso_parser.erl](src/aeso_parser.erl)), the [Sophia Syntax Documentation](docs/sophia_syntax.md) should be updated to include the new syntax.
-- If a PR introduces a new library, the public interface of the new library should be fully documented in the [Sophia Standard Library Documentation](docs/sophia_stdlib.md).
-- If a PR introduces a new compiler option, the new option should be documented in the file
-[aeso_compiler.md](docs/aeso_compiler.md).
-
-### Tests
-
-- If a PR introduces new syntax (e.g. changes in [aeso_syntax.erl](src/aeso_syntax.erl), [aeso_scan.erl](src/aeso_scan.erl), or [aeso_parser.erl](src/aeso_parser.erl)), the contract [all_syntax.aes](test/contracts/all_syntax.aes) should be updated to include the new syntax.
-- If a PR fixes a bug, the code that replicates the bug should be added as a new passing test contract.
-- If a PR introduces a new feature, add tests for both successful and failing usage of that feature. In order to run the entire compilation pipeline and to avoid erroring during intermediate steps, failing tests should not be mixed with the successful ones.
-
-### Source Code

-# aeso_aci
-
-### Module
-
-### aeso_aci
-
-The ACI interface encoder and decoder.
-
-### Description
-
-This module provides an interface to generate and convert between
-Sophia contracts and a suitable JSON encoding of contract
-interface. As yet the interface is very basic.
-
-Encoding this contract:
-
-```
-contract Answers =
-  record state = { a : answers }
-  type answers() = map(string, int)
-
-  stateful function init() = { a = {} }
-  private function the_answer() = 42
-  function new_answer(q : string, a : int) : answers() = { [q] = a }
-```
-
-generates the following JSON structure representing the contract interface:
-
-
-``` json
-{
-  "contract": {
-    "functions": [
-      {
-        "arguments": [],
-        "name": "init",
-        "returns": "Answers.state",
-        "stateful": true
-      },
-      {
-        "arguments": [
-          {
-            "name": "q",
-            "type": "string"
-          },
-          {
-            "name": "a",
-            "type": "int"
-          }
-        ],
-        "name": "new_answer",
-        "returns": {
-          "map": [
-            "string",
-            "int"
-          ]
-        },
-        "stateful": false
-      }
-    ],
-    "name": "Answers",
-    "state": {
-      "record": [
-        {
-          "name": "a",
-          "type": "Answers.answers"
-        }
-      ]
-    },
-    "typedefs": [
-      {
-        "name": "answers",
-        "typedef": {
-          "map": [
-            "string",
-            "int"
-          ]
-        },
-        "vars": []
-      }
-    ]
-  }
-}
-```
-
-When that encoding is decoded the following include definition is generated:
-
-```
-contract Answers =
-  record state = {a : Answers.answers}
-  type answers = map(string, int)
-  function init : () => Answers.state
-  function new_answer : (string, int) => map(string, int)
-```
-
-### Types
-```erlang
--type aci_type()  :: json | string.
--type json()      :: jsx:json_term().
--type json_text() :: binary().
-```
-
-### Exports
-
-#### contract\_interface(aci\_type(), string()) -> {ok, json() | string()} | {error, term()}
-
-Generate the JSON encoding of the interface to a contract. The type definitions
-and non-private functions are included in the JSON string.
-
-#### render\_aci\_json(json() | json\_text()) -> string().
-
-Take a JSON encoding of a contract interface and generate a contract interface
-that can be included in another contract.
-
-### Example run
-
-This is an example of using the ACI generator from an Erlang shell. The file
-called `aci_test.aes` contains the contract in the description from which we
-want to generate files `aci_test.json` which is the JSON encoding of the
-contract interface and `aci_test.include` which is the contract definition to
-be included inside another contract.
-
-``` erlang
-1> {ok,Contract} = file:read_file("aci_test.aes").
-{ok,<<"contract Answers =\n  record state = { a : answers }\n  type answers() = map(string, int)\n\n  stateful function"...>>}
-2> {ok,JsonACI} = aeso_aci:contract_interface(json, Contract).

-                    returns => #{<<"map">> => [<<"string">>,<<"int">>]},
-                    stateful => false}],

-             typedefs =>
-                 [#{name => <<"answers">>,
-                    typedef => #{<<"map">> => [<<"string">>,<<"int">>]},
-                    vars => []}]}}]}
-3> file:write_file("aci_test.aci", jsx:encode(JsonACI)).
-ok
-4> {ok,InterfaceStub} = aeso_aci:render_aci_json(JsonACI).
-{ok,<<"contract Answers =\n  record state = {a : Answers.answers}\n  type answers = map(string, int)\n  function init "...>>}
-5> file:write_file("aci_test.include", InterfaceStub).
-ok
-6> jsx:prettify(jsx:encode(JsonACI)).
-<<"[\n  {\n    \"contract\": {\n      \"functions\": [\n        {\n          \"arguments\": [],\n          \"name\": \"init\",\n        "...>>
-```
-
-The final call to `jsx:prettify(jsx:encode(JsonACI))` returns the encoding in a
-more easily readable form. This is what is shown in the description above.

-# Introduction
-Sophia is a functional language designed for smart contract development. It is strongly typed and has
-restricted mutable state.
-
-Sophia is customized for smart contracts, which can be published
-to a blockchain. Thus some features of conventional
-languages, such as floating point arithmetic, are not present in Sophia, and
-some [æternity blockchain](https://aeternity.com) specific primitives, constructions and types have been added.
-
-!!! Note
-    - For rapid prototyping of smart contracts check out [AEstudio](https://studio.aepps.com/)!
-    - For playing around and diving deeper into the language itself check out the [REPL](https://repl.aeternity.io/)!

-Sophia uses Python-style layout rules to group declarations and statements. A
-layout block with more than one element must start on a separate line and be
-indented more than the currently enclosing layout block. Blocks with a single
-element can be written on the same line as the previous token.
-
-Each element of the block must share the same indentation and no part of an
-element may be indented less than the indentation of the block. For instance
-
-```sophia
-contract Layout =
-  function foo() = 0  // no layout
-  function bar() =    // layout block starts on next line
-    let x = foo()     // indented more than 2 spaces
-    x
-     + 1              // the '+' is indented more than the 'x'
-```
-
-## Notation
-
-In describing the syntax below, we use the following conventions:
-
-- Upper-case identifiers denote non-terminals (like `Expr`) or terminals with
-  some associated value (like `Id`).
-- Keywords and symbols are enclosed in single quotes: `'let'` or `'='`.
-- Choices are separated by vertical bars: `|`.
-- Optional elements are enclosed in `[` square brackets `]`.
-- `(` Parentheses `)` are used for grouping.
-- Zero or more repetitions are denoted by a postfix `*`, and one or more
-  repetitions by a `+`.
-- `Block(X)` denotes a layout block of `X`s.
-- `Sep(X, S)` is short for `[X (S X)*]`, i.e. a possibly empty sequence of `X`s
-  separated by `S`s.
-- `Sep1(X, S)` is short for `X (S X)*`, i.e. same as `Sep`, but must not be empty.
-
-
-## Declarations
-
-A Sophia file consists of a sequence of *declarations* in a layout block.
-
-```c
-File ::= Block(TopDecl)
-
-TopDecl ::= ['payable'] ['main'] 'contract' Con [Implement] '=' Block(Decl)
-          | 'contract' 'interface' Con [Implement] '=' Block(Decl)
-          | 'namespace' Con '=' Block(Decl)
-          | '@compiler' PragmaOp Version
-          | 'include' String
-          | Using
-
-Implement ::= ':' Sep1(Con, ',')
-
-Decl ::= 'type'     Id ['(' TVar* ')'] '=' TypeAlias
-       | 'record'   Id ['(' TVar* ')'] '=' RecordType
-       | 'datatype' Id ['(' TVar* ')'] '=' DataType
-       | 'let'      Id [':' Type]      '=' Expr
-       | (EModifier* 'entrypoint' | FModifier* 'function') Block(FunDecl)
-       | Using
-
-FunDecl ::= Id ':' Type                             // Type signature
-          | Id Args [':' Type] '=' Block(Stmt)      // Definition
-          | Id Args [':' Type] Block(GuardedDef)    // Guarded definitions
-
-GuardedDef ::= '|' Sep1(Expr, ',') '=' Block(Stmt)
-
-Using ::= 'using' Con ['as' Con] [UsingParts]
-UsingParts ::= 'for' '[' Sep1(Id, ',') ']'
-             | 'hiding' '[' Sep1(Id, ',') ']'
-
-PragmaOp ::= '<' | '=<' | '==' | '>=' | '>'
-Version  ::= Sep1(Int, '.')
-
-EModifier ::= 'payable' | 'stateful'
-FModifier ::= 'stateful' | 'private'
-
-Args ::= '(' Sep(Pattern, ',') ')'
-```
-
-Contract declarations must appear at the top-level.
-
-For example,
-```sophia
-contract Test =
-  type t = int
-  entrypoint add (x : t, y : t) = x + y
-```
-
-There are three forms of type declarations: type aliases (declared with the
-`type` keyword), record type definitions (`record`) and data type definitions
-(`datatype`):
-
-```c
-TypeAlias  ::= Type
-RecordType ::= '{' Sep(FieldType, ',') '}'
-DataType   ::= Sep1(ConDecl, '|')
-
-FieldType  ::= Id ':' Type
-ConDecl    ::= Con ['(' Sep1(Type, ',') ')']
-```
-
-For example,
-```sophia
-record   point('a) = {x : 'a, y : 'a}
-datatype shape('a) = Circle(point('a), 'a) | Rect(point('a), point('a))
-type     int_shape = shape(int)
-```
-
-## Types
-
-```c
-Type ::= Domain '=>' Type             // Function type
-       | Type '(' Sep(Type, ',') ')'  // Type application
-       | '(' Type ')'                 // Parens
-       | 'unit' | Sep(Type, '*')      // Tuples
-       | Id | QId | TVar
-
-Domain ::= Type                       // Single argument
-         | '(' Sep(Type, ',') ')'     // Multiple arguments
-```
-
-The function type arrow associates to the right.
-
-Example,
-```sophia
-'a => list('a) => (int * list('a))
-```
-
-## Statements
-
-Function bodies are blocks of *statements*, where a statement is one of the following
-
-```c
-Stmt ::= 'switch' '(' Expr ')' Block(Case)
-       | 'if' '(' Expr ')' Block(Stmt)
-       | 'elif' '(' Expr ')' Block(Stmt)
-       | 'else' Block(Stmt)
-       | 'let' LetDef
-       | Using
-       | Expr
-
-LetDef ::= Id Args [':' Type] '=' Block(Stmt)   // Function definition
-         | Pattern '=' Block(Stmt)              // Value definition
-
-Case    ::= Pattern '=>' Block(Stmt)
-          | Pattern Block(GuardedCase)
-
-GuardedCase ::= '|' Sep1(Expr, ',') '=>' Block(Stmt)
-
-Pattern ::= Expr
-```
-
-`if` statements can be followed by zero or more `elif` statements and an optional final `else` statement. For example,
-
-```sophia
-let x : int = 4
-switch(f(x))
-  None => 0
-  Some(y) =>
-    if(y > 10)
-      "too big"
-    elif(y < 3)
-      "too small"
-    else
-      "just right"
-```
-
-## Expressions
-
-```c
-Expr ::= '(' LamArgs ')' '=>' Block(Stmt)   // Anonymous function    (x) => x + 1
-       | '(' BinOp ')'                      // Operator lambda       (+)
-       | 'if' '(' Expr ')' Expr 'else' Expr // If expression         if(x < y) y else x
-       | Expr ':' Type                      // Type annotation       5 : int
-       | Expr BinOp Expr                    // Binary operator       x + y
-       | UnOp Expr                          // Unary operator        ! b
-       | Expr '(' Sep(Expr, ',') ')'        // Application           f(x, y)
-       | Expr '.' Id                        // Projection            state.x
-       | Expr '[' Expr ']'                  // Map lookup            map[key]
-       | Expr '{' Sep(FieldUpdate, ',') '}' // Record or map update  r{ fld[key].x = y }
-       | '[' Sep(Expr, ',') ']'             // List                  [1, 2, 3]
-       | '[' Expr '|' Sep(Generator, ',') ']'
-                                            // List comprehension    [k | x <- [1], if (f(x)), let k = x+1]
-       | '[' Expr '..' Expr ']'             // List range            [1..n]
-       | '{' Sep(FieldUpdate, ',') '}'      // Record or map value   {x = 0, y = 1}, {[key] = val}
-       | '(' Expr ')'                       // Parens                (1 + 2) * 3
-       | '(' Expr '=' Expr ')'              // Assign pattern        (y = x::_)
-       | Id | Con | QId | QCon              // Identifiers           x, None, Map.member, AELib.Token
-       | Int | Bytes | String | Char        // Literals              123, 0xff, #00abc123, "foo", '%'
-       | AccountAddress | ContractAddress   // Chain identifiers
-       | OracleAddress | OracleQueryId      // Chain identifiers
-       | '???'                              // Hole expression       1 + ???
-
-Generator ::= Pattern '<-' Expr   // Generator
-            | 'if' '(' Expr ')'   // Guard
-            | LetDef              // Definition
-
-LamArgs ::= '(' Sep(LamArg, ',') ')'
-LamArg  ::= Id [':' Type]
-
-FieldUpdate ::= Path '=' Expr
-Path ::= Id                 // Record field
-       | '[' Expr ']'       // Map key
-       | Path '.' Id        // Nested record field
-       | Path '[' Expr ']'  // Nested map key
-
-BinOp ::= '||' | '&&' | '<' | '>' | '=<' | '>=' | '==' | '!='
-        | '::' | '++' | '+' | '-' | '*' | '/' | 'mod' | '^'
-        | '|>'

+<p>The ACI interface encoder and decoder.</p>
+<h3 id="description">Description</h3>
+<p>This module provides an interface to generate and convert between
+Sophia contracts and a suitable JSON encoding of contract
+interface. As yet the interface is very basic.</p>
+<p>Encoding this contract:</p>
+<div class="highlight"><pre><span></span><code>contract Answers =
+  record state = { a : answers }
+  type answers() = map(string, int)
+
+  stateful function init() = { a = {} }
+  private function the_answer() = 42
+  function new_answer(q : string, a : int) : answers() = { [q] = a }
+</code></pre></div>
+<p>generates the following JSON structure representing the contract interface:</p>

+<p>Sophia is a functional language designed for smart contract development. It is strongly typed and has
+restricted mutable state.</p>
+<p>Sophia is customized for smart contracts, which can be published
+to a blockchain. Thus some features of conventional
+languages, such as floating point arithmetic, are not present in Sophia, and
+some <a href="https://aeternity.com">æternity blockchain</a> specific primitives, constructions and types have been added.</p>

+<h2 id="layout-blocks">Layout blocks</h2>
+<p>Sophia uses Python-style layout rules to group declarations and statements. A
+layout block with more than one element must start on a separate line and be
+indented more than the currently enclosing layout block. Blocks with a single
+element can be written on the same line as the previous token.</p>
+<p>Each element of the block must share the same indentation and no part of an
+element may be indented less than the indentation of the block. For instance</p>
+<div class="highlight"><pre><span></span><code><span class="k">contract</span><span class="w"> </span><span class="nf">Layout</span><span class="w"> </span><span class="ow">=</span>

+</code></pre></div>
+<h2 id="notation">Notation</h2>
+<p>In describing the syntax below, we use the following conventions:</p>
+<ul>
+<li>Upper-case identifiers denote non-terminals (like <code>Expr</code>) or terminals with
+  some associated value (like <code>Id</code>).</li>
+<li>Keywords and symbols are enclosed in single quotes: <code>'let'</code> or <code>'='</code>.</li>
+<li>Choices are separated by vertical bars: <code>|</code>.</li>
+<li>Optional elements are enclosed in <code>[</code> square brackets <code>]</code>.</li>
+<li><code>(</code> Parentheses <code>)</code> are used for grouping.</li>
+<li>Zero or more repetitions are denoted by a postfix <code>*</code>, and one or more
+  repetitions by a <code>+</code>.</li>
+<li><code>Block(X)</code> denotes a layout block of <code>X</code>s.</li>
+<li><code>Sep(X, S)</code> is short for <code>[X (S X)*]</code>, i.e. a possibly empty sequence of <code>X</code>s
+  separated by <code>S</code>s.</li>
+<li><code>Sep1(X, S)</code> is short for <code>X (S X)*</code>, i.e. same as <code>Sep</code>, but must not be empty.</li>
+</ul>
+<h2 id="declarations">Declarations</h2>
+<p>A Sophia file consists of a sequence of <em>declarations</em> in a layout block.</p>
