I really dislike using boolean operators on anything that is not a boolean. I recently made an esception to my rule and got punished... Yeah it is skill issue on my part that I tried to check that a variable equal to 0 was not None using "if variable...". But many programming rules are there to avoid bugs caused by this kind of inattention.
