so there's no point talking about freezing a function, module,
Neither of which are immutable.
Okay, so what would freezing a function be useful for, then? What is your use-case here? Mutable objects can't be used as dict keys, so there is a strong use-case for versions of them which can. But when arbitrary attributes don't contribute to equality, freezing becomes largely irrelevant. I can subclass frozenset and allow attributes. Do we then need a "really frozen set"? What is the point of such a protocol, given that my subclass is still hashable? Or are you just arguing for the sake of arguing? ChrisA
