The big advantage to my reorganization of your loop is that it doesn't have an unused "x" binding.
The other advantage is that the expressions bound to "x" and "y" are not repeated at the beginning of the loop and at the end. Also, (and this is less clear cut, more opinion), it's typical for a loop binding to be something that depends on the previous iteration of the loop, e.g.: (loop [x 10] (when (> x 0) (recur (dec x))) In this example, the value of "x" always depends on the previous loop iteration. Contrast that with: (loop [x (read-line)] (do (println "Hello " x) (recur (read-line))) In this example, the value of "x" is arbitrary, and doesn't really have anything to do with the previous loop iteration. And thus, IMHO, it shouldn't be a loop binding.
