I don't want to pull all the pieces together.

Meta programing wouldn't likely help, there are too many rules 
about how your interface and inheritance needs to combine with 
the parent model that any meta programming would hide the intent.

I still don't believe interfaces are needed, nor your example of 
multiple inheritance.
