This is the part that bothers me, I think. It seems like all these adaptation requests would be a huge burden on the framework developer. In PyGUI, for example, I currently have about 2 or 3 dozen classes. Should I be defining and registering a formal protocol for every one of those? Should I be putting adaptation calls in all of the few hundred places where an object might come in from somewhere else and I'm expecting it to be one of my classes? Does it even stop there? Should I be doing IInteger(x) on every x someone gives me that I'm going to use as an integer? What you're proposing seems to be tantamount to a sort of dynamic version of static typing, with much of its bookkeeping overhead. Python tries to avoid this by not going in for that sort of thing. -- Greg _______________________________________________ Python-3000 mailing list Python-3000@python.org http://mail.python.org/mailman/listinfo/python-3000 Unsubscribe: http://mail.python.org/mailman/options/python-3000/archive%40mail-archive.com
