I'm looking to do something like this:
(defprotocol Addable
(add-fields [this]))
(defrecord MyRecord [a b]
Addable
(add-fields [this] (+ a b)))
;;; Magic happens here
(defn indirect-adder [a b]
(add-fields (MyRecord. a b)))
(with-definition-of-add-fields-changed-to (fn [_] "hi mom")
(indirect-adder 1 2)
=> "hi mom" ; rather than 3
I expect there are no tricks like :dynamic true <http://blog.n01se.net/?p=134>
that work, but I thought I'd check.
