+ * ap applies a list of functions to a list of values.
+ *
+ * Dispatches to the `ap` method of the second argument, if present. Also
+ * treats curried functions as applicatives.
+ *
+ * @func
+ * @memberOf R
+ * @since v0.3.0
+ * @category Function
+ * @sig [a -> b] -> [a] -> [b]
+ * @sig Apply f => f (a -> b) -> f a -> f b
+ * @sig (r -> a -> b) -> (r -> a) -> (r -> b)
+ * @param {*} applyF
+ * @param {*} applyX
+ * @return {*}
+ * @example
+ *
+ *      R.ap([R.multiply(2), R.add(3)], [1,2,3]); //=> [2, 4, 6, 4, 5, 6]
+ *      R.ap([R.concat('tasty '), R.toUpper], ['pizza', 'salad']); //=> ["tasty pizza", "tasty salad", "PIZZA", "SALAD"]
+ *
+ *      // R.ap can also be used as S combinator
+ *      // when only two functions are passed
+ *      R.ap(R.concat, R.toUpper)('Ramda') //=> 'RamdaRAMDA'
+ * @symb R.ap([f, g], [a, b]) = [f(a), f(b), g(a), g(b)]
