Example
(examples are from proposal)
function add(x, y) { return x + y; }
const addOne = add(1, ?); // apply from the left
addOne(2); // 3
const addTen = add(?, 10); // apply from the right
addTen(2); // 12
let newScore = player.score
|> add(7, ?)
|> clamp(0, 100, ?); // shallow stack, the pipe to `clamp` is the same frame as the pipe to `add`.
