There are several interpretations of the word "trivial." One is "easy"
or "simple" (where one could dispute whethe
Thanks Meikel for such an insightfull feedback. Its hard to imagine so much
thought goes into writing trivial looking functions.

Thanks everybody,
Clojure community is awesome .. and also I just wanted to learn to use
lazy-seq that is why it was written in the way I showed you all.
Thanks again.

Eh. This is weird. It seems that (partition n coll) drops the last
part of coll if it's not a multiple of n in size; e.g. (partition 3 [1
2 3 4 5]) yields ((1 2 3)) and not ((1 2 3) (4 5)). (partition n n []
coll) does do that though.
OTOH,
(mapcat identity (partition 1 n coll))

Hello everybody,
I just needed a function for every-nth element in a sequence.. I know it
can be trivially implemented as ..
(defn every-nth [n coll]
(letfn [(evn [cn s]
(when s
(if (= cn 1)
(lazy-seq (cons (first s) (evn n (next s
