That is why I think Sather has it done right. You can only inherit from 
something abstract, i.e., sth that has no implementation at all. Reuse 
of implementation in Sather is separate from inheritance of interface.

disclaimer: It has been a long while since I've followed Sather so 
history could have diverged from what I know.
