"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.
