   That's what I would have thought, but this is not true across all
   implementations.  The TI Explorer's class prototype doesn't exhibit
   this behavior.  Apparently until an instance is initialized, it
   doesn't have values even for its class allocated slots!  Bizarre, but
   true.  (OK, so TI Lisp is not really up-to-date, but we need to
   support that platform).  
I believe the that the TI implementation is correct the the face of X3J13. It
is not up-to-date because the MOP didn't exist when I implemented it.
