:method and :multi work just fine together -- at least within a single class. In fact, the various compilers in PCT (PAST::Compiler and POST::Compiler) rely on multiple dispatch working properly for methods. Where the semantics get a little weird is when a subclass defines a multimethod that overloads multimethods of the same name in the parent class -- in this case the subclass multimethod completely hides the parent class multimethod.
