Actually what you did is pretty clever, Jim. It even relies on stable

If we could find some way to effectively communicate the way Zope works
(and what goes on in Jim Fulton's head), the fact that this works
wouldn't be so surprising. Achieving this is not just about documenting
interfaces, however. It's also about new design patterns that are made
available through the concept of acquisition. I hope that the books
being written about Zope go into depth on the new concepts.
