New submission from Carl Friedrich Bolz-Tereick <[email protected]>:
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'}
```
