More properly "automatic delegation" -- in Python, you
code it up in __getattr__; in my dream-version of Java
(not existing afaik) you could just declaratively state
"and all methods of interfaces X and Y which I have
not implemented just delegate to the following expression
based on my attributes", with at least interface
granularity (if not method by method).
