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.
