we recently found use for an orbiting iterator, specifically a circular one, which effectively wraps at the start/end of a bounded range. (The domain is digital signal processing.)

That sounds like what CGAL calls a Circulator; c.f. http://doc.cgal.org/ latest/Circulator/classCirculator.html

Sounds to me like a ring_view - (ring_view?) which has been discussed for a long time.

I couldn't find anything on this with a cursory search, could you link to something?

Thanks, cheers. Jeremy
