A couple of reasons: 1. In reviewing the code, I didn't find an obvious way to store cached values. Anything but a non-trivial change would suggest the need for a PEP of its own to document new behavior. 2. I've been hoping that PEP 649 would be adopted, making such a hack or any plan to cache type hints moot. Paul
