true and false was guaranteed.
Am I being overly cautious or should I change them all to one form or the other?
This is fine. The C/C++ standards guarantee that a bool, when converted
to an integer, is 1 or 0 (the pedantically correct way of saying this
depends on which standard/revision, but effectively that sums it up).
It's pretty convenient/elegant at times. Personally, I exploit it when
that's the case, but be more explicit if it has potential to be
confusing.
