 * @typeParam T - Element type produced by the source iterable.

 * @returns An array containing every element yielded by `src` in iteration order.
 *
 * @example
 * ```ts
 * const snapshot = _toArray(new Set([1, 2, 3]));
 * console.log(snapshot); // [1, 2, 3]
 * ```
 *
 * or using the curried version:
 * ```ts
 * const snapshot = pipeInto(new Set([1, 2, 3]), toArray());
 * console.log(snapshot); // [1, 2, 3]
 * ```
