Well, it would be a problem if the semantics need to get hairy to 
support the syntax.  To continue quoting from Tim, "If the 
implementation is hard to explain, it's a bad idea."

So I think I would prefer to only handle built-in integer types for now.  
I guess the PEP should state that more explicitly?

Thanks for your other comments, I'll keep them in mind.
