I don't use ITERATE, but that's more because I haven't felt the need than because I dislike it; it looks much better designed to me than LOOP. Maybe I should give it a try. As for giving my opinion weight, it's definitely a minority opinion among CLers, but I think we're a significant minority; I don't think I'm the only one. DO seems a little complicated at first, it's true, but once you understand it, the parts all fit together neatly. The only thing I wish had been done differently is the sense of the exit test -- currently it acts like "until" (the loop is exited when the test form evaluates to true), but the consensus of modern programming languages is that "while" behavior (exiting when the test is false) is more natural.
