According to docs
__bool__ can return 1 or 0 instead of True or False.
However, when I ran the following code:

Python 3.1 (r31:73574, Jun 26 2009, 20:21:35) [MSC v.1500 32 bit
(Intel)] on win32
>>> class Spam():
	def __bool__(self):
		return 1

>>> if Spam():

I got the following error:
Traceback (most recent call last):
  File "<pyshell#72>", line 1, in <module>
    if Spam():
TypeError: __bool__ should return bool or int, returned int

So, do I misunderstand the docs or is it an error in them?
