This works if #foo just implies one method "foo".

But suppose it were more general, like:

  #drawable which implies methods draw2,drawfast,drawbuffered,etc..

and

  #foldable which implies methods iter,sample,map,to_list,etc...

We would like to avoid calling every implied method.


Thanks,

Peng
