Ah yeah, didn't remember that constraint in Python. I thought I read something about a future version fixing that when it comes to just type hints, but I suppose that wouldn't work here, since it's not really a type hint, right?

Yup, you're thinking of "postponed evaluation of annotations", which is currently optional with `from __future__ import annotations`. But as you said, would not fix the circular import here.
