My view is that boolean values should be treated as boolean and not as numbers, ALWAYS.

There are NO instances where booleans should be used as numbers, despite the fact that C/C++ allows it, there should always be an explicit conversion. It might lead to slightly smaller code, but usually its far less readable & maintainable.

(I've just recently had to tidy up somebody's very sloppy code, where the values of TRUE & FALSE were used numerically, there were functions that returned multiple values such as TRUE/FALSE/ERROR1/ERROR2 the values being used in a switch statement checking for 1,0,-1,-2 - hence my current strong views on correct use of booleans & not assuming values for TRUE/FALSE)
