731 ;;; "Note that two methods with identical specializers, but with different
732 ;;; qualifiers, are not ordered by the algorithm described in Step 2 of the
733 ;;; method selection and combination process described in Section 7.6.6
734 ;;; (Method Selection and Combination). Normally the two methods play different
735 ;;; roles in the effective method because they have different qualifiers, and
736 ;;; no matter how they are ordered in the result of Step 2, the effective
737 ;;; method is the same. If the two methods play the same role and their order
738 ;;; matters, an error is signaled. This happens as part of the qualifier
739 ;;; pattern matching in define-method-combination."
