I may be biased since I learned C before Python and learned Python 
before it had a Boolean type, but I'd think that having False==0 and 
True==1 is not that surprising for most programmers.

This idiom should slowly disappear now we have a clean syntax for such 
expressions.

I suppose this mostly have to do with one's background.
