Assuming interfaces == AOP == "true delegation", I agree.
"True delegation" where the self of the delegatee becomes the self of
the delegator allows you to implement a form of "horizontal"
inheritance, a more powerful form of composition.
There was some talk of it appearing in Visual Works 4, due out in Jan,
but it didn't make the cut. It's also being considered for Visual
Age.
