However, it seems to me that toggling the value with the idiom: --b; is aesthetically preferable to the more elaborate: b = !b; In fact, I've seen at least one person make this complaint in freenode's ##c++ IRC channel. Given the potential usefulness of `--b' and the relative uselessness of `++b', it would seem more practical for the C++ standard to have deprecated (if not allowed) `--b' and instead forbidden `++b' (rather than the other way around).
