This proposal is irrelevant for experienced users but it may be useful for newcomers. After having delivered several introductory Symfony training, I can say that when someone adds `return "some string...";` in their controller, the error message is confusing:

Maybe we can reword it a bit? (I'm open for suggestions to improve the error message)
