+;;; Return two values. First value is a function to be stored in
+;;; effective slot definition SLOTD for reading it with
+;;; SLOT-VALUE-USING-CLASS, setting it with (SETF
+;;; SLOT-VALUE-USING-CLASS) or testing it with
+;;; SLOT-BOUNDP-USING-CLASS. GF is one of these generic functions,
+;;; TYPE is one of the symbols READER, WRITER, BOUNDP. CLASS is
+;;; SLOTD's class.
+;;;
+;;; Second value is true if the function returned is one of the
+;;; optimized standard functions for the purpose, which are used
+;;; when only standard methods are applicable.
+;;;
+;;; FIXME: Change all these wacky function names to something sane.
