     * We attach two autoloaders:
     *
     * - The first is _prepended_ to handle new classes and add aliases for
     *   legacy classes. PHP expects any interfaces implemented, classes
     *   extended, or traits used when declaring class_alias() to exist and/or
     *   be autoloadable already at the time of declaration. If not, it will
     *   raise a fatal error. This autoloader helps mitigate errors in such
     *   situations.
     *
     * - The second is _appended_ in order to create aliases for legacy
     *   classes.
