You probably want a Ref here to coordinate the changes on the
sequence.
(defn get-step
[queue]
(dosync
(let [q @queue]
(alter queue rest)
q)))
; Or for convenience if you like...
(def get-step-c
(let [queue (ref your-seq-here)]
(partial get-item queue)))
Each worker can call get-step on your seq Ref. Then the current step
in the seq is returned and the Ref is updated to contain the next
step. The seq is returned, so you can do nil-checking of (seq q) or
working with (first q) and what you normally do with seqs.
Sincerely
Meikel
