[New-bugs-announce] [issue32960] dataclasses: disallow inheritance between frozen and non-frozen classes

[Eric V. Smith]

New submission from Eric V. Smith <eric at trueblade.com>:

This is a temporary measure until we can better define how frozen inheritance should work. In the meantime, disallow:

- frozen inherited from non-frozen
- non-frozen inherited from frozen
