/**
 * Macroable Trait.
 *
 * The Macroable trait provides a simple implementation of the "macro" functionality
 * that allows classes to dynamically add methods at runtime. This trait is adapted
 * from a similar implementation in the Laravel framework.
 *
 * @see https://github.com/laravel/framework/blob/10.x/src/Illuminate/Macroable/Traits/Macroable.php
 *
 * Laravel is an open-source PHP framework, which includes the original version of
 * this trait. The source code in this file has been modified to suit the specific
 * needs of the PHP-Flasher project.
