"Automatic delegation" is what I want.  I've even invented my own little syntax 
for it:

public SomeClass extends Fubar implements List(myList), OtherThing {

   private AbstractList myList = new ArrayList();

...

}


where the parenthesis in the interface list is a forward declaration to a field 
that will be the delegate for that particular interface.  It really shouldn't 
be that hard to do, just a few synthetic methods.

I really rather upset that we aren't getting something like this with Java 8.  
I don't see any reason not to fix this right now, honestly.
