Besides, an you're assuming only people write code. Code writes code, too, and sometimes it's easier to let the later compiler optimize out an unnecessary if test than to do all the side-effect analysis yourself. Consider if (c = getchar());. That could be generated for a "don't care" entry in a stream.
