Jeremy's answer is good for how to do a for loop in idiomatic Clojure.

If you really want an imperative-style for loop in Clojure, you can create one with this macro:

(defmacro for-loop [[sym init check change :as params] & steps]
 `(loop [~sym ~init value# nil]
    (if ~check
      (let [new-value# (do ~@steps)]
        (recur ~change new-value#))
      value#)))

Usage as follows:

(for-loop [i 0 (< i 10) (inc i)] 
  (println i))
