[Python-Dev] set.remove feature/bug

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

Regards Paolino
