--- Comment #3 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Right, it's incorrect to assume begin and end return the same type for a range.
Use std::common_iterator if you need to turn an iterator and its sentinel into
a single type:
using CI = std::common_iterator<decltype(r.begin()), decltype(r.end())>;
foo(CI(r.begin()), CI(r.end()));
