Would it be OK to implement our own constexpr char_traits(just replace ::compare, ::length), then use 
boost::basic_string_view<char, patched_char_traits<char>> as our CONSTEXPR_STRING_VIEW and compare views with 
constexpr boost::string_view::compare(a, b) == 0? This way seems to work on my g++-6 which prevents 
reinventing the wheel.
