Use new-style classes throughout --------------------------------

The following classes will inherit explicitly from the built-in object type, to make all classes in the module part of the new-style type hierarchy. [snip] They already do. metaclass = type is found in unittest.py. Not in the copy I have. Is that in 3.x only, or in 2.x also?

While your retort is accurate, I think it's unintentionally deceptive, because you didn't finish your thought.. Benjamin is actually still correct:

Python 2.5.1 (r251:54863, Apr 18 2007, 08:51:08) [MSC v.1310 32 bit (Intel)] on win32 Type "help", "copyright", "credits" or "license" for more information.

import unittest isinstance(unittest.TestCase, type) True type(unittest.TestCase) <type 'type'>
