sort of the whole point. If you don't care whether it gives the right
answer you might as well just leave the status quo.

rking on (about 60k
lines of C++) for anywhere && and || appear on the same line. I got 49
hits, 29 where && was evaluated before ||, 20 the other way around. (All

&&-inside-|| seems to be slightly more common, I'd certainly dispute
James's claim that it's "far more common".
