504 ;;; qualifiers, are not ordered by the algorithm described in Step 2 of the
505 ;;; method selection and combination process described in Section 7.6.6
506 ;;; (Method Selection and Combination). Normally the two methods play different
507 ;;; roles in the effective method because they have different qualifiers, and
508 ;;; no matter how they are ordered in the result of Step 2, the effective
509 ;;; method is the same. If the two methods play the same role and their order
