Intels IAPX 432 processor incorporated this idea in hardware.  It was
slow.  This is not necessarily because of the basic idea.  It may have
just been a bad implementation.  It would be worth while to get the databook
for the 432 it is quite interesting.  The 432 went a little bit further.
It basically "knows" the type of every data structure and enforces certain
rules as to what can be done with things of each type.
