-  The ANSI syntax for non-STANDARD method combination types in CLOS is
-       (DEFGENERIC FOO (X) (:METHOD-COMBINATION PROGN))

-       (DEFMETHOD FOO ((X BAR)) (PRINT 'NUMBER))
-  the error mesage is not easy to understand:
-          INVALID-METHOD-ERROR was called outside the dynamic scope

-       DEFINE-METHOD-COMBINATION or a method on the generic

-  It would be better if it were more informative, a la
-          The method combination type for this method (STANDARD) does
-       not match the method combination type for the generic function
-       (PROGN).
-  Also, after you make the mistake of omitting the PROGN qualifier
-  on a DEFMETHOD, doing a new DEFMETHOD with the correct qualifier
-  no longer works:
-       (DEFMETHOD FOO PROGN ((X BAR)) (PRINT 'NUMBER))
