You can use qualified keywords with an hierarchy.
(def your-hierarchy
(-> (make-hierarchy)
(derive ::hello ::anything)
(derive ::world ::anything)
(derive ::city ::anything)
(derive ::us ::anything)))
(defmulti foo
your-dispatch-fn-here
:hierarchy your-hierarchy)
(defmethod foo [::anything ::hello ::anything ::anything] (str "I'm
method 1"))
(defmethod foo [::world ::anything ::us ::anything] (str "I'm
method 2"))
(defmethod foo [::city ::anything ::us ::anything] (str "I'm
method 3"))
