I don't know what the solution is (Steven has some ideas, but I don't

able to reasonably get tail-const ranges from const ranges. Otherwise,
as soon
as you get a const range, it's pretty much useless.
I wrote a proof-of-concept tail-const range framework at some point, and
posted it to BugZilla[1]. It shows that such a thing is possible in the
language as-is, however I don't think it would win a beauty contest.
This is a hard problem to get right, and I'd love to see Steven's ideas.
