--- Comment #3 from Jonathan Wakely <redi at gcc dot gnu.org> --- Also, ranges::advance doesn't use the custom advance for path::iterator. Maybe we should make path::iterator satisfy the random_access_iterator concept. We can't do that for directory iterators though, so maybe we want another customization point for internal use.
