Returns whether this matcher is convertible to the given type.

If it is so convertible, store in *Specificity a value corresponding to the "specificity" of the converted matcher to the given context, and in *LeastDerivedKind the least derived matcher kind which would result in the same matcher overload. Zero specificity indicates that this conversion would produce a trivial matcher that will either always or never match. Such matchers are excluded from code completion results.

◆ isPolymorphic()
