types can be autocompleted from the controller, and in the twig template too

Ha, this is the first time I'm reading about this feature in Twig. If you don't mind, I'll put this somewhere at the bottom of my priorities, since I don't use it myself. But if you can pull this off, feel free to create a PR, but do make sure to read the Contributing Guidelines first.

It's okay, I don't have the time to do implement it myself now and I have no experience with Go, but I may take a look at it some day if you don't do it by then.
