;;;; built-in classes
-;;; FIXME: This was the portable PCL way of setting up
-;;; *BUILT-IN-CLASSES*, but in SBCL (as in CMU CL) it's almost
-;;; entirely wasted motion, since it's immediately overwritten by a
-;;; result mostly derived from SB-KERNEL::*BUILT-IN-CLASSES*. However,
-;;; we can't just delete it, since the fifth element from each entry
-;;; (a prototype of the class) is still in the final result. It would
-;;; be nice to clean this up so that the other, never-used stuff is
-;;; gone, perhaps finding a tidier way to represent examples of each
-;;; class, too.
-;;;
-;;; FIXME: This can probably be blown away after bootstrapping.
-;;; And SB-KERNEL::*BUILT-IN-CLASSES*, too..
