Subject: [boost] [iterator] Orbiting iterators

Hi,
just wondering what the mood in Boost.Iterator is for new features? At work
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.)
Implementation details aside, does this feature sound desirable to the
library?
I call it an "orbiting" iterator because it is a specific (and useful) case
of the more general rho-shaped orbiting iterator. The theory behind it is
in chapter 2 of Elements of Programming, which happens to be the free
sample chapter available:

Anyway, if there is interest, I'll make a pull request.
Cheers.
Jeremy
