Nikita Sobolev <m...@sobolevn.me> added the comment:
This happens to all `lru_cache` calls, where we deal with container types.
Example:
```
from functools import lru_cache
@lru_cache(typed=True)
def test(arg):
return str(arg)
print(test((1, 'a'))) # (1, 'a')
print(test((True, 'a'))) # (1, 'a')
```
Moveover, this behavior is not tested in `test_functools`:
