 No, that's still too confused

I think the problem is with the term "generator function" because what we call "generator function" is neither a generator nor a function.  It is a callable that returns a generator.   To our excuse, this abuse of language is not uncommon.  People often say "integer function" when they mean a function with integer domain and range (or even just range).
