If you're only interested in the side effects of the computation and not the result say:
(map #(println %) [1 2 3 4]) you can use dorun rather than doall as it doesn't retain the head (therefore requiring less memory). (dorun (map #(println %) [1 2 3 4])) Also, if you see yourself mapping over a sequence inside a dorun (as above) you should consider doseq: (doseq [el [1 2 3 4]] (println el)) which requires even less allocation as it doesn't use map which creates a new seq.
