Comment (by marshall):

 I'm confused.
 I tried this:


 {{{
 struct S { std::string_view sv; };

 int main () {
     static_assert(
 std::is_trivially_move_constructible<std::string_view>::value, "" );
     static_assert( std::is_trivially_move_constructible<S>::value, "" );
     static_assert( std::is_trivially_constructible<std::string_view,
 std::string_view&&>::value, "" );
     }

 }}}

 and it compiled w/o error.  (clang, libc++)
