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.)
Must  be useful to some people, so yes.
(Needs tests, an example and docs of course to add to Boost).
Thanks, Paul, always good to hear from you. Yes, the response so far
convinces me that it is a useful and fairly elementary feature that has
simply been overlooked.

Sounds to me like a ring_view - (ring_view?) which has been discussed
for
a long time.
We could bikeshed about the name?
Orbiting iterator, ring_iterator, circulator,  never-ending ... ;-)
Yes, although I can tell you now that my proposal will be for a class
circular_iterator. I just meant the word "orbiting" in
reference to the broader concept.

So now the question remains: is there a maintainer of Boost.Iterator that,
in principle, wants this? Who is/are the maintainer(s)? I found reference
to a user jeffrey.hellrung, is that current?

Cheers.
