what's the correct syntax for new clojure?

[wubbie]

Hi,

What's the correct syntax for this code -- from clojure manual.
(import '(java.util.concurrent Executors))
(defn test‐stm [nitems nthreads niters]
(let [refs (map ref (replicate nitems 0))
pool (. Executors (newFixedThreadPool nthreads))
tasks (map (fn [t]
(fn []
(dotimes n niters
(dosync
(doseq r refs
(alter r + 1 t))))))
(range nthreads))]
(doseq future (. pool (invokeAll tasks))
(. future (get)))
(. pool (shutdown))
(map deref refs)))

There's a correct, updated version here: http://clojure.org/concurrent_programming

(import '(java.util.concurrent Executors))
(defn test-stm [nitems nthreads niters]

(let [refs (map ref (replicate nitems 0))

pool (Executors/newFixedThreadPool nthreads)

tasks (map (fn [t]
(fn []
(dotimes [n niters]
(dosync
(doseq [r refs]
(alter r + 1 t))))))
(range nthreads))]

(doseq [future (.invokeAll pool tasks)]
(.get future))
(.shutdown pool)
(map deref refs)))
