My thought is then you can control access to the inner pointer 
better that way. You couldn't even pass this struct to a function 
without calling some kind of method, which could return a 
different type to indicate that it is a lent pointer.

It also wouldn't need to be reference counted, since the refcount 
is always going to be 1 because copying it is impossible.

Yes, I'm just trying to do what we can with the language today.
