In a class, `__hash__ = None` means the instances are not hashable... but in a dataclass decorator, `hash=None` means they are?2) Change the default value for "hash" from "None" to "False". This might take a little effort because there is currently an oddity where setting hash=False causes it to be hashable. I'm pretty sure this wasn't intended ;-)I haven't looked at this yet.I think the hashing logic explained in https://bugs.python.org/issue32513#msg310830 is correct. It uses hash=None as the default, so that frozen=True objects are hashable
