/**
 * Optionally, pass this as `$resolver` to {@see Dispatcher::__construct()} to provide
 * integration with a dependency injection container - for example:
 *
 *     $dispatcher = new Dispatcher(
 *         [
 *             RouterMiddleware::class,
 *             ErrorMiddleware::class,
 *         ],
 *         new InteropResolver($container)
 *     );
 *
 * Note that this resolver will ignore any middleware component that is not a string - so you
 * can mix component names with regular middleware closures, callable objects, and so on.
 *
 * You can use class-names or other component names, depending on what your container supports.
