 * Returns an array of key-value pairs for every entry in the array or tuple.
 *
 * Note that this is not the same as `Array.entries(A)`,
 * which returns an iterable interator.
 *
 * @example
 * ```ts
 * ArrayPlus.Entries<Array<string | number>> // Array<[number, string | number]>
 * ArrayPlus.Entries<[1, 2, 3]> // [[0, 1], [1, 2], [2, 3]]
 * ```
