There is a nice method in Behavior that is invoked when ever the annotations of a class's methods change, would be nice to use that to make Meta more causally connected. Would be nice if someone has time to do that, refer to

instanceMethodsChanged "One of the receiver's instance methods which has meta annotations changed. The method may have been removed, or may be about to be added. Because this action may be invoked many times, and because the change it reflects may not be completed yet, the receiver's response should probably be fairly limited (such as flushing a cache) rather than something more proactive, such as actively repopulating a data structure that records the state of things."

Maybe that is also useful for you, Andrea.
