@noisebleed for #136 - at the moment the system gives you an empty Response object.
The ResponseFactory will give an empty PSR-7 Response object to the dispatcher, which will pass this to controller upon invoke :)
@dracony would be nice for you to create a METHOD on App.php to perform such translation. Then it can be easily unit tested.
The larger picture here is to clean up App.php as we go and gradually make App.php into a series of smaller and more testable classes.
Are you okay with this ?
