;;;; KLUDGE: The primitive objects here may look like self-contained
;;;; definitions, but in general they're not. In particular, if you
;;;; try to add a slot to them, beware of the following:
-;;;; * (mysterious crashes which occur after changing the length
-;;;; of SIMPLE-FUN, just adding a new slot not even doing anything
-;;;; with it, still dunno why)
;;;; * The GC scavenging code (and for all I know other GC code too)
;;;; is not automatically generated from these layouts, but instead
;;;; was hand-written to correspond to them. The offsets are
