Indeed. I was going to make a post asking for advice on high-level delegation (basically you have a generic mostly-OO framework, which the user extends mostly by subclassing, but how do the generic classes know about the user-extened classes?). I knew of many solutions, but all had significant drawbacks. But this seems like it'd work great, maybe with a few minor inconveniences but nothing like the icky hacks I've been using. Ironic, since I myself posted a very simple example of how to do this with a class hook here on c.l.python a while back. But I'll have to review the license and see how it works with what I have.
