I can't contact sourceforge bug tracker sorry.

set.remove is trying to freeze sets when they are used as keys.No matter if an __hash__ method is defined.

This is incoherent with Set.remove and dict.__delete__ & co.

If this is a feature ,then I ask strongly to keep sets module in the stdlib for ever.

Or if there is a workaround, please tell me here because python-list didn't help.

class H(set): def __hash__(self):return id(self) s=H()

f=set() f.add(s) f.remove(s) # this fails
