The __call__ of a class is the default constructor (the standard __new__/__init__ dance). Static and class methods of the class can also be used to support the interfaces of the class itself. > So my continuing thick-headed questions is: What does classProvides > really mean from a practical standpoint? Some kind of use case? Well, it sounds like you've already identified it as a way to describe the interface of the class (as a factory). It's not unusual for code using the component architecture to locate factories for objects by looking up a utility that provides the factory interface. That allows some nice ways to re-use composition-based constructs. -Fred -- Fred L.
