Is hash=id inside a class enough to use a set (sets.Set before 2.5) derived class instance as a key to a mapping? It is hash=lambda self:id(self) that is terribly slow ,it needs a faster way to state that to let them be useful as key to mapping as all set operations will pipe into the mechanism .In my application that function is eating time like hell, and will keep on doing it even with the PEP proposed .OT probably.
