8 * Creates a function that invokes `func` with the `this` binding of the
9 * created function and arguments from `start` and beyond provided as
10 * an array.
11 *
12 * **Note:** This method is based on the
13 * [rest parameter](https://mdn.io/rest_parameters).

19 * @param {Function} func The function to apply a rest parameter to.
20 * @param {number} [start=func.length-1] The start position of the rest parameter.
