While I know it, and I've used it... it still does not seem the best thing to 
do in name of readability and maintainability. I prefer the conditional 
statement, because it clearly expresses the underlying logic, to any use of a 
side effect as mentioned above. But that's me, your mileage may vary.

[btw, I believe that this has something to do with the fact that my first 
language was Pascal, where the true=1/false=0 identity doesn't hold by 
definition. C programmers are more used to this idiom than I am]
