If there is no base class, then "if there's a global variable named __metaclass__, it is used." So my guess would be that adding a mere

Unless you define a class that inherits from a base class defined in another module. __metaclass__ does not apply when there are base classes. I prefer to inherit from object, because it is more explicit, and avoids possible confusion when some classes have classic bases. Jeremy
