This is usually the Thrush combinator[0], exists in other languages as well, and can be informally defined as:

  f(g(x)) = g(x) |> f

Not quite. Note that the Elixir pipe puts the left hand of the pipe as the first argument in the right-hand function. E.g.

    x |> f(y) = f(x, y)

As a result, the Elixir variant cannot be defined as a well-typed function, but must be a macro.
