Unless I'm misunderstanding, couldn't one of __getattr__ or
__getattribute__ make mapping other methods you don't override very
simple and practical, not to mention fully automated with 2-3 lines of
code? In particular, __getattr__ would seem good for your use since
it is only called for attributes that couldn't already be located.
I've had code that wrapped underlying objects in a number of cases, and
always found that to be a pretty robust mechanism.
