Potential use case for anonymous PHP classes to translate between middleware types

anonymous_middleware.php

<?php
$conduit->pipe(new class implements MiddlewareInterface {
    public function __invoke($request, $response, $next)
    {
        $laravelRequest = mungePsr7ToLaravelRequest($request);
        $laravelNext    = function ($request) use ($next, $response) {
            $request = ;
            return $next(mungeLaravelToPsr7Request($request), $response)
        };
        $laravelMiddleware = new SomeLaravelMiddleware();
        $response = $laravelMiddleware->handle($laravelRequest, $laravelNext);
        return mungeLaravelToPsr2Response($response);
    }
});
