totally forgot about it. :o/

Not everything is chunked, but data-structures like vectors produce
chunked-seqs.

Hi Andy,
Lazy sequences are realised in chunks of 32.
You can see this by running:
(take 1 (map prn (range)))
(0
1
..
30
31
nil)
Thanks,
Ambrose

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
