I note that http://www.boost.org/libs/range/doc/range.html uses the term "closed-open range." The term used in prior art is "half-open range." Is there a good reason to invent new terminology here?

For some reason my replies don't get to the list yet. So I'll post using the web-interface.

To answer the question: otherwise, how do you now which end that is open and which that is closed?

By understanding the conventional meaning of half-open, I happen to know what a half-open range is, but when you say "closed-open" without defining it, I wonder if I know what you're talking about. You could define it, but then if you're really worried someone will be confused by half-open, you could define _that_ and stay consistent with normal terminology. And incidentally, AFAICT nobody uses a range built the other way (it's difficult to work with), so half-open always means "closed at the beginning." -- Dave Abrahams Boost Consulting www.boost-consulting.com
