I'm confused by what you're saying here - these are examples of passing a
map, not of passing varargs.
If you want to pass a map, you'll need a set up like:
(defmulti test-html :language) ;; :language here is a keyword being used
as a function of one arg (the map)
(defmethod test-html :html [the-map]
(str (:data the-map) " will be transformed into html"))
(defmethod test-html :java-fx [the-map]
(str (:data the-map) " will be transformed into javafx"))
Invoked like:
(test-html {:language :html :data "hello"})
