About "Object in list" expression

[Mirons]

Hi everybody! I'm having a very annoying problem with Python: I need
to check if a (mutable) object is part of a list but the usual
expression return True also if the object isn't there. I've
implemented both __hash__ and __eq__, but still no result. what does
"in" implementation use for comparison (Python is 2.6)?
