    Yeah, you see, when they design these geometric machines they
    take this into consideration and treat the location 2 as 'special' -
    when you use a pointer that points to anything pointing to it (or
    anywhere near it, within reason [ except 0, q.v. ]),
    the last location you referenced is automatically squared.  Any
    arithmetic overflow is propagated out thru the carry bit into
    location 0.  ;^()
