std::string_view?

[John Muehlhausen]

error: invalid operands to binary expression
('nonstd::sv_lite::basic_string_view<char, std::char_traits<char> >' and
'basic_string_view<char>')

This from
   val == "str"sv

Is there a way to access a util::string_view as a std::string_view other
than re-building a std::string_view from data()/size() ?
