You can grok it, Just.
Wrap the top object in a proxy.
Everytime you get a __getattr__, return another proxy. Build these
into a chain. When something actually tries to use the last proxy in
the chain, you poke around the chain looking for something tasty to
return to the poor, unsuspecting user.
Unlike metaclasses the theory won't explode your brain.
