  The following reply to a query on comp.lang.clos give one more inch
  of evidence for the utility of the phrases "direct instances" and
  "indirect" or "derived" instances.

      Subject: RE: accessing clos objects
      . . .
         I have implemented such a metaclass using the accessors for
      class name-object mapping as a model. This scheme allows
      (class-direct-instances class), (instance-name object), 
      (find-instance obect), and (setf (instance-name object) ...) on any 
      instances of classes of this new metaclass.
      . . . 
  Out of curiosity, is this email disucssion list "dead" now?  Is there
  going to be any further discussion of the "pink" book?
