Hi all
I noticed something strange here while explaining decorators to someone. Not any real use code, but I think it's worth mentioning. When I access a class attribute, on a class with a custom metaclass with a __getattribute__ method, the method is used when acessing some attribute directly with the class object, but not when you do it from the instance. <code type='prompt'> >>> class M(type): ... def __getattribute__(cls, attr): ... print cls, attr ... return type.__getattribute__(cls, attr) ... >>> class C(object): ... __metaclass__ = M ... >>> C.x = 'foo' >>> C.x <class '__main__.C'> x 'foo' >>> o = C() >>> o.x 'foo' >>> </code> Someone at freenode #python channel involved with python-dev sprint suggested it might be a bug, worth mentioning... to me it seems like a decision to avoid some problems with method and descriptors creation, since someone using metaclasses and custom __getattribute__ at the same time is asking for trouble, but... I googled for it and tried to find something on the list but, nothing. From the source it seems like a generic wrapper is used. What's the real case here ?
