/**
 * Returns the empty value of its argument's type. Ramda defines the empty
 * value of Array (`[]`), Object (`{}`), String (`''`), and Arguments. Other
 * types are supported if they define `<Type>.empty`,
 * `<Type>.prototype.empty` or implement the
 * [FantasyLand Monoid spec](https://github.com/fantasyland/fantasy-land#monoid).
 *
 * Dispatches to the `empty` method of the first argument, if present.
 *
 * @func
 * @memberOf R
 * @since v0.3.0
 * @category Function
 * @sig a -> a
 * @param {*} x
 * @return {*}
 * @example
 *
 *      R.empty(Just(42));      //=> Nothing()
 *      R.empty([1, 2, 3]);     //=> []
 *      R.empty('unicorns');    //=> ''
 *      R.empty({x: 1, y: 2});  //=> {}
