  no, but some Common Lisp implementations provide access to heap walkers
  from their memory management subsystems that return a list of all "live"
  objects of a particular system type.  STANDARD-INSTANCE is typically such
  a system type, but you can easily test for the correct classness
  yourself.  which Common Lisp are you using?
