for (;;) {
    //Something to be done repeatedly
}

I have seen this sort of thing used a lot, but I think it is rather strange... Wouldn't it be much clearer to say while (TRUE), or something along those lines?

I'm guessing that (as is the reason for many-a-programmer to resort to cryptic code) this is a tiny margin faster?

Why, and is it REALLY worth it? If so, why not just define it this way:

#DEFINE while(TRUE) for(;;)
