       class std::experimental::basic_string_view< _CharT, _Traits >"A non-owning reference to a string.

       TemplateParameters_CharT Type of character
           _Traits Traits for character type, defaults to char_traits<_CharT>.

       A basic_string_view looks like this:

       _CharT*    _M_str
