True is False

Usually I prefer to rant about the oddities of ruby but this time it's python.

Python 2.5.2 (r252:60911, Jan 20 2010, 21:48:48)
[GCC 4.2.4 (Ubuntu 4.2.4-1ubuntu3)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> True
True
>>> False
False
>>> True,False=False,True
>>> True
False
>>> False
True
>>> False=True
>>> True = True is False
>>> False = True is False
>>> True
True
>>> False
False

Well, if it was lisp I wouldn't be surprised….
