Believe it or not, but we're on the same wavelength:

I'm thinking about proxy-methods a la aspect oriented programming, more than
whole proxy objects.  e.g. cooperative __{g,s}et{attr,item}__ methods that
implement observer semantics and can forward to base-class methods.  Whole
object proxies have the problem that object identity and type information is
obscured in ways that are contrary to standard Python idioms.
