True, but I've had bad experiences doing that. See, for example, http://groups.google.com/group/comp.lang.python/browse_thread/thread/10cfe2affc265ac where I tried to subclass 'int'. More importantly, subclassing means that people have to keep re-inventing the same methods. Having a single implementation would save time, not to mention the speed advantages of implementing them in the hosting language (C, Java, .NET, etc). -- http://mail.python.org/mailman/listinfo/python-list
