Well, if we want something like std::vector to be a Range, then we have
to accept that at least *some* Ranges do propagate constness.  And I'm
pretty sure that we don't want other Ranges (std::pair<char*,char*>) to
propagate constness.  So unless the documentation says otherwise, I
would assume that the concept doesn't say anything about whether
constness is propagated.  If you want to write generic Range code you
have to account for both cases.
