What problem?

(Yeah, I know, I could read your original post now but I think you'll be

fact that contains() adds a __setitem__ declaration to your interface.)

*Usually* we only deal with contains() within IContainer-derived 
interfaces anyway. That doesn't mean you have to go and implement 
IContainer now.
