That's what drove C99 to standardize a bool type.   Indeed, Python may be the
only non-trivial C project I've worked on that didn't #define its own
boolean gimmick for internal use.

I'd like to note too that a Boolean concept is needed all over the place,
despite that it's not an official type.   It shows up in docstrings even now:

>>> print hasattr.__doc__
hasattr(object,  name) -> Boolean
...

>>> import os
>>> print os.isatty.__doc__ 
isatty(fd) -> Boolean
...
>>>

That's not an exhaustive list, just a tease.
