I have manage to write something like this. But nothing more, all my
ideas are wrong, because bad knowledge about evaluation and namespace
expansion time.
(defmacro map-fnc [ & methods ]
`(reduce (fn[ acc# m# ] (assoc acc# (str (first m#)) (list 'fn (rest
m#)) )) {} '~methods ))
(map-fnc (function1 [] "hello")
(function2 [a] (println a)))
