## Summary This behavior dates back to a Pyflakes commit (5fc37cbd), which was used to allow this test to pass: ```py from __future__ import annotations T: object def f(t: T): pass def g(t: 'T'): pass ``` But, I think this is an error. Mypy and Pyright don't accept it -- you can only use variables as type annotations if they're type aliases (i.e., annotated with `TypeAlias`), in which case, there has to be an assignment on the right-hand side (see: [PEP 613](https://peps.python.org/pep-0613/)). |
