Then probably something like this will help me out
(defn defmutualmethods [multifn dispatch-val & fn-tail]
(defmethod multifn dispatch-val fn-tail)
(defmethod multifn (reverse dispatch-val) fn-tail))
Nevertheless i'm making things more complex now because it does two things
now! But it will make it easier for me i guess.
its just a thought
