New submission from Alex Samuel [EMAIL PROTECTED]:
Methods of set and frozenset that return new set or frozenset instances
return instances of subclasses, but these instances are not initialized
correctly. In the attached code sample, z is an instance of MySet but
MySet.__new__ and
Mark Dickinson [EMAIL PROTECTED] added the comment:
The bug is that the set operations return instances of the subclass,
rather than instances of set.
This is already fixed for 3.0: see issue 1721812. It was deemed too risky
to backport the change to 2.x.
