(def my-ref (ref 1))
(defn update-my-ref
[new-value]
(dosync
(alter my-ref #(+ % new-value))
(ref-history-count my-ref)))
Hi guys ;
I am trying to understand (ref-history-count ref) . I thought it counts the
number of "old" values in the ref. But in all my tests, its always
returning zero. How is it used?
