I was a bit puzzled. Clojure seems to provide both avenues. The "Common Lisp" version: (for [i (range 1 10) :when (even? i) :while (< i 5)] i) A Haskell-y version (according to the article): (->> (range 1 10) (take-while #(< % 5)) (filter even?)) Using Clojure's transducers: (into [] (comp (take-while #(< % 5)) (filter even?)) (range 1 10))
