 * Positive lookbehind assertion.

 * A positive lookbehind assertion is a zero-width assertion that matches a group of characters only if it is preceded by a specific group of characters.
 *
 * @example
 * ```ts
 * lookbehind("a");
 * // /(?<=a)/
 *
 * lookbehind(["a", "b", "c"]);
 * // /(?<=abc)/
