If Python had had a boolean type from the beginning, it
probably wouldn't have been a subclass of int -- that was
more or less forced by backwards compatibility issues.

I'm not sure that's all that much different from Pascal,
where you can use ord() to turn a boolean into an int
if you want to. At least you're being explicit.
