A couple of reactions:
- Could this kind of thing be achieved using multiple inheritance with
properly constructed mixins? (For example, do the Common Lisp or Eiffel
folks use mixins to this effect?)
- I've looked a very little at Aspect-Oriented Programming, which was pretty
much at the research stage when I peeked. Based on that little bit of
knowledge, this looks like it might be along the same lines (maybe an
application of AOP). Sorry, I don't have a good URL handy, but it should
be a good search term for your favorite engine.
