Fast¹ `curry`

and `unstage`

with *cyclical placeholder semantics*²

```
const {_, curry, unstage} = require('furry');
const a = 1, b = 2, c = 3;
const f = curry((a, b, c) => a - b * c);
const g = unstage(3, a => b => c => a - b * c);
[
f(a, b, c),
g(a, b, c),
f(_, _, c, _)(b, a),
g(_, _, c, _)(b, a),
f(_)(_)(c)(_)(b)(a),
g(_)(_)(c)(_)(b)(a),
f(_, _, c, _, b, a),
g(_, _, c, _, b, a)
]
.every(x => x === -5)

Cyclical placeholder semanticsRather than the placeholder flipping the argument with the next, the argument is flipped with the last. To learn more, check out my Gist explaining the idea.
