Why would an subclass of object that doesn't redefine either __eq__ or __ne__ have a different behavior for inequality than object itself? Bar never defined __eq__, so it shouldn't have an implicit __ne__ any more than object itself does... Saying that Bar has an implicit __ne__ that object doesn't is answering how this happens, but it's not a why; is there a reason why this should be the case, or is this a bug (either in spec or in code) that should be fixed?
