I agree that common guidelines are a good thing. But you still can’t prevent programmers from choosing their own “happy subsets” of even the official guideline. Simple example: suppose I choose, as my own special discipline (which I have sometimes used) never to use `break` to break out of a `for` or `while` loop, but instead insist on providing a label and using `break label;`. The rationale is that whenever I see a plain `break` in my code, I always know it’s for a `switch` statement. If you agree with this idea, then I win: I get to use my happy subset. If you disagree, then I really win: it demonstrates that you and I would choose different happy subsets! :-) :-) :-) (Don’t mind me; I’m feeling puckish today.) —Guy
