494 ;;; When two methods are in the same method group and have the same
495 ;;; specializers, their sort order within the group may be ambiguous. Therefore,
496 ;;; we should throw an error when we have two methods in the same group with
497 ;;; the same specializers /as long as/ we have more than one method group
498 ;;; or our single method group qualifier-pattern is not *. This resolves the
499 ;;; apparent conflict with the above 'It is also possible to bypass' language.
501 ;;; The language specifying this behavior is:
502 ;;; "Note that two methods with identical specializers, but with different
503 ;;; qualifiers, are not ordered by the algorithm described in Step 2 of the
504 ;;; method selection and combination process described in Section 7.6.6
505 ;;; (Method Selection and Combination). Normally the two methods play different
506 ;;; roles in the effective method because they have different qualifiers, and
507 ;;; no matter how they are ordered in the result of Step 2, the effective
508 ;;; method is the same. If the two methods play the same role and their order
509 ;;; matters, an error is signaled. This happens as part of the qualifier
