That's another reason I prefer `char const*` - I don't find it elegant when
compiler built-ins have to know about user-defined types such as `string_view`.
But I don't think it is necessary for the built-ins to know about string_view, the builtins are usually wrapped into something that can take a `const char[N]` from the built-in and turn it into a string view.
