Redefining a let'd variable in Clojure loop

Question

OK. I\'ve been tinkering with Clojure and I continually run into the same problem. Let\'s take this little fragment of code:

(let [x 128]
  (while (> x 1)
            


        

Answer 1

You could more idiomatically use iterate and take-while instead,

user> (->> 128
           (iterate #(/ % 2))
           (take-while (partial < 1)))

(128 64 32 16 8 4 2)
user>
