You do it in a different language that isn't haskel or ml and show me the result, then we can judge.

You'd btw probably write it as.

  (->> (range)
       (map #(repeat % (odd? %)))
       (apply concat)
       (take 1000)

If you want it more readable.

You missed a closing paren :)

It shows that Lisp programmers really don't care about balancing parenthesis, because editors do that for them.

Yeah, I really love the new parinfer stuff :D

whops ^^°
