Re: [std-proposals] Templated Circular Buffer Container

This was earlier proposed as P0059, but appears to have seen little work in
the last few years.
Note, however, that this is a span-like container and doesn't own the
elements. You need to
create an array and apply the ring_span to it.

I would be interested in seeing this picked up again.
