Thanks. Yeah, so ring_span is a view, which I guess is more or less the
Range equivalent.

What I'm talking about is a generalization of the CGAL Circulator and
Boost.Geometry ever_circling_iterator, and is in fact almost identical to
the latter.
So another way of saying this is that I just want to lift
ever_circling_iterator out of Boost.Geometry for generic use.

Cheers.
