--- Comment #5 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Your mistake is thinking that the iterators of views are like the iterators
you're used to.

They're not.

They have different properties (e.g. they might not be copyable, they might=
 not
have operator->, they might not define iterator_category) and
std::iterator_traits is for use with the old kind of iterators, not the new
ones.=
