I tried playing around with the new primitive type hints and got the
following weird behavior on [org.clojure/clojure "1.7.0-beta2"]:
(defn ^longs init-state [] (long-array 1))
(defn ^long store-state [^longs c ^long a] (aset c 0 a))
running the following line resulted in an exception:
(let [x (init-state)]
(store-state x 5))
1. Caused by java.lang.VerifyError

while the following line worked just fine:

and also this works fine:
(def a (init-state))
(store-state a 5)
(aget a 0) ;; 5
What do you think?
