PEP 563 interacts in weird ways with constant folding. running the following code: ``` from __future__ import annotations def f(a: 5 + 7) -> a 39: return 12 print(f.__annotations__) ``` I would expect this output: ``` {'a': '5 + 7', 'return': 'a 39'} ``` But I get: ``` {'a': '12', 'return': 'a ** 39'} ```
