Currently |> works only on single argument functions, rendering it quite useless in many situations. Following Elixir's approach to it, we could make it only on the first (last?) parameter that is piped:

function i(x) = x
function f(x, y) = x - y
function g(x) = x

21 |> i |> f(37) |> g

which would mean

g(f(i(21), 37))
