/**
 * Returns the last element of the source iterable that satisfies the optional predicate.
 *
 * @typeParam T - Element type produced by the source iterable.
 * @param src - Source iterable to enumerate.
 * @param pred - Predicate receiving each element and its index; the most recent truthy match is returned.
 * @returns The last element matching `pred`.
 * @throws Error Thrown when no element satisfies `pred`.
 *
 * @example
 * ```ts
 * const result = _last([1, 2, 3, 4], (value) => value % 2 === 0);
 * console.log(result); // 4
 * ```
 *
 * or using the curried version:
 * ```ts
 * const result = pipeInto(
 *   [1, 2, 3, 4],
 *   last((value) => value % 2 === 0)
 * );
 * console.log(result); // 4
 * ```
