Hmm, well. Are you really trying to make it so Python won't have to make a specialized subclass (err, subPMC?) of this system? If so, then it'll probably need drastic changes.. I'm a Python hacker who's pretty familiar with its object system. If you want, I can offer up some explanations/advice for making this system usable directly by Python. As it stands, an implementation of the Python object system could definitely be implemented _in terms of_ what you have now, but, for example, the method system that you have worked out now would be totally unusable (afaics), as instance methods have some pretty whacky, dynamic semantics. It'd probably have to be implemented in terms of properties. The problem, of course, is that either you go more static and make the very dynamic, reflective languages like Python harder to implement (or prevent them from making use of your existing abstractions like methods, as explained above), or you go more dynamic and make the more static languages (like Haskell?) slower because they'd have to implement their features in terms of dynamic ones, when a lot of the information could be available at compile-time. But who knows, maybe it could be made modular enough (i.e., more interface-oriented?) to allow the best of both worlds -- I'm far too novice wrt Parrot to figure out what it'd look like, unfortunately. I've been lurking this thread for a while, very interested, and unsure if I should offer my suggestions for making the object system more compatible with Python, and this looks like a great chance for me to jump in. :-) -- Twisted | Christopher Armstrong: International Man of Twistery Radix | Release Manager, Twisted Project ---------+ http://twistedmatrix.com/users/radix.twistd/
