Clojure to Slang

2. Clojure:

3. (println (take 25 (map (* % %) (range))))

4. (defn squared [x] (* x x))
(println (take 25 (map (* % %) (range))))

5. (defn squared [x] (* x x))
(println (take 25 (map squared (range))))

6. (println (take 25 (map squared (range))))

7. (println (take 25 (map squared range)))

8. (println (take 25 range.map(squared)))

9. (println range.map(squared).take(25))

10. range.map(squared).take(25).println

11. Slang.
