Hi,
(defn exchange!
[a b & {:keys [getter setter] {getter identity setter (fn [_ v] v)}}]
(let [av @a bv @b]
(alter a setter (getter bv))
(alter b setter (getter av))))
(defn exchange-color!
[a b]
(exchange! a b :getter :color :setter #(assoc %1 :color %2)))
(exchange-color! a b)
Something like that?
Sincerely
Meikel
