class xlist(list):
def __freeze__(self):
return tuple(self)
Shouldn't that be:
class xlist(list):
def __freeze__(self):
return tuple(map(freeze, self))
"Should dicts and sets automatically freeze their mutable keys?"
Dictionaries don't have mutable keys, but it is of my opinion that a
container which is frozen should have its contents frozen as well.
