so i want only the first 10 results.
you could:
(def zip
I am a newbie, but seems that for comprehension are lazy lists:
user (take 5 (for [x (range 20) :when (do (printf *%d* x) (= (rem x 2)
1))] x))
(*0* *1* *2* *3* 1 *4* *5* 3 *6* *7* 5 *8* *9* 7 9)
So, I think that you should use take :)

Or should I just use (take 10 ) on the for ?
Michael
As far as I know the number of yields is not available for testing, so
you have to use take
user= (take 10 (for [x (range 1000) :when (= (rem x 2) 1)] x))
(1 3 5 7 9 11 13 15 17 19)
