When I know that all instances of classes inheriting from object have a namespace, then I would expect either that all objects have a namespace or that it was inherited from object. I would expect instantiating object to be the simplest and best way to get a namespace. But ... >>> o = object() >>> o.foo = 7 Traceback (most recent call last): File "<stdin>", line 1, in <module> AttributeError: 'object' object has no attribute 'foo' >>> o.__slot__ Traceback (most recent call last): File "<stdin>", line 1, in <module> AttributeError: 'object' object has no attribute '__slot__' >>> class O(object): pass >>> o = O() >>> o.foo = 7 That object is kind of "pure virtual" seems to me to be a confusing special case without any advantages. Why can't object be instantiated directly? Is that explained and documented anywhere? /Mads -- http://mail.python.org/mailman/listinfo/python-list
