/**
 * Returns a curried equivalent of the provided function.
 * The curried function has two unusual capabilities.
 * First, its arguments needn't be provided one at a time.
 * If f is a ternary function and g is curry(f), the following are equivalent:
 *
 * - `g(1)(2)(3)`
 * - `g(1)(2, 3)`
 * - `g(1, 2)(3)`
 * - `g(1, 2, 3)`
 * Secondly, the special placeholder value __ may be used to specify "gaps",
 * allowing partial application of any combination of arguments,
 * regardless of their positions. If g is as above and _ is placeholder,
 * the following are equivalent:
 * - `g(1, 2, 3)`
 * - `g(__, 2, 3)(1)`
 * - `g(__, __, 3)(1)(2)`
 * - `g(__, __, 3)(1, 2)`
 * - `g(__, 2)(1)(3)`
 * - `g(__, 2)(1, 3)`
 * - `g(__, 2)(__, 3)(1)`
