  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?
