Just as a sidenote, some of us were trained in languages where integersare
often used in the place of booleans.
For example, my first computer science class in college was taught in a
language called Scheme (a variant of LISP) which IIRC had no typed boolean.
So we all learned that "not false is true enough" meaning that for a given
variable type, there was one and only one defined value that was false, and
anything else was true.
While this doesn't always hold true, it does in a good many popular
languages.
The long and the short of it is that I read "not zero" as true and "zero" as
false.
In the long run, I think we can put this in the "personal preference"
file -- at least until MM breaks the standard on how they interpret integers
in a boolean evaluation.
