Clojure works on a chunked basis for performance reasons...THe size of a chunk is 32 elements - thus you would actually get 32 printouts if you supplied a collection larger than 31 elements.

Hi,

Can someone correct my misunderstanding here. I was lead to believe that map produced a lazy sequence, so why do I get three printed trace lines in the following code :

user=> (take 1 (map #(do (println (str "trace:" %)) %) [1 2 3]))
(trace:1
trace:2
trace:3
1)

Thanks for your help

Andy
