-;;;; everything needing to be loaded before everything else. This is
-;;;; the first file which really exercises the type stuff. This stuff
-;;;; is also somewhat implementation-dependent in that implementations
-;;;; may want to precompute other types which are important to them.

-;;; DEFSTRUCT due to DEF!STRUCT not understanding raw slots -- it's
