Variant types always box. They always have the reference. I understand
you're arguing that type constructors should work the same way.
Well, maybe they should have. I'm not sure I'd like it if that was
changed now, however. Working code wouldn't cease to work- it'd just be
less memory efficient. But you'd always have the extra reference, even if
you didn't need it.
