 * This method is like `_.curry` except that arguments are applied to `func`

 * in the manner of `_.partialRight` instead of `_.partial`.

 *

 * The `_.curryRight.placeholder` value, which defaults to `_` in monolithic

 * builds, may be used as a placeholder for provided arguments.

 *

 * **Note:** This method doesn't set the "length" property of curried functions.

 *

 * @static

 * @memberOf _

 * @since 3.0.0

 * @category Function

 * @param {Function} func The function to curry.

 * @param {number} [arity=func.length] The arity of `func`.

 * @param- {Object} [guard] Enables use as an iteratee for methods like `_.map`.

 * @returns {Function} Returns the new curried function.

 * @example

 *

 * var abc = function(a, b, c) {

 *   return [a, b, c];

 * };

 *

 * var curried = _.curryRight(abc);

 *

 * curried(3)(2)(1);

 * // => [1, 2, 3]

 *

 * curried(2, 3)(1);

 * // => [1, 2, 3]

 *

 * curried(1, 2, 3);

 * // => [1, 2, 3]

 *

 * // Curried with placeholders.

 * curried(3)(1, _)(2);

 * // => [1, 2, 3]
