frameworks are defined. They very rarely specify or give any guarantee
of when or whom will send a given message to a given object.
This makes indeed difficult to subclass and override methods in a sturdy
way.
This is probably a reason why OO programmers nowadays tend to distance
themselves from inheritance (using so called "flat" hierarchies), and
like "final" methods a lot, which basically denies OO itself.
Otherwise, for your question, you didn't mention any metaclass. I'm not
sure about it, but I would expect such methods from AMOP to be used
consistently only when you define your own metaclasses.
