---------------------------------------------------------+------------------
 When manufacturing a range for the passed in containers,
 range_detail::make_range() calls range_detail::is_char_ptr() which will
 takes its (unused) parameter by value just so `0L` can be returned.

 This means make_range() can't be used with non-copyable classes.
