Hey @rafaqz, have you seen this?

Yeah that's amazing. I saw discussion on slack but I'm really in PhD mode now so haven't looked.

But just gave it a read. Seems pretty similar to what you can do here already, like checking all of the interfaces for a package. And a similar anonymous function approach but with macro magic so its just checking methods and return types. Looks good to me.

I hope it happens and we don't have to work on this!
