;;; CMUCL comment (from Gerd Moellmann/Pierre Mai, 2002-10-19):

;;; According to AMOP, COMPUTE-EFFECTIVE-METHOD should return two
;;; values.  Alas, the second value is only vaguely described in AMOP,
;;; and, when asked on 2002-10-18, Gregor Kiczales said he couldn't
;;; remember what the second value was supposed to be.  So, PCL's
;;; COMPUTE-EFFECTIVE-METHOD returns one value as do Allegro and
;;; Lispworks.
