While the templated constructor for basic_string_view is constexpr, this
constructor for string_view cannot be used in a constexpr context because
char_traits<char>::length isn't constexpr. :-(  See LWG 2232
<http://cplusplus.github.io/LWG/lwg-active.html#2232>.

I've been told it works this way by design...

So yes, we do need the macro.
