Heh... this is one of those areas where there seem to be two distinct 
camps with little grey area. :-) For the record, I'm in the "Thou shalt 
not use an integral value as the result in thy boolean test" camp with 
Diane here.  Zero meaning false, non-zero meaning true is merely a 
convention (which is simple to grasp and not as error-prone as many 
other conventions, admittedly, but still a convention).

In the end, I think that being an electrical engineer -- where we study 
hole flow and active low signals are common -- makes me value the 
clarity of an explicit integral test, even if the code compiles the same.

Even so... I'd hope that nobody starts wasting time by submitting 
patches for this (one way or the other).
