* @func
* @memberOf R

* @category Function
* @sig ((a, b, c, ...) -> z) -> (b -> a -> c -> ... -> z)
* @param {Function} fn The function to invoke with its first two parameters reversed.
* @return {*} The result of invoking `fn` with its first two parameters' order reversed.
* @example
*
* const mergeThree = (a, b, c) => [].concat(a, b, c);
*
* mergeThree(1, 2, 3); //=> [1, 2, 3]
*
* R.flip(mergeThree)(1, 2, 3); //=> [2, 1, 3]
