title: Clojure read-string
body: <p>(read-string "01") returns 1.</p>
  
  <p>In fact read-string from "01" to "07" returns the correct answer. But while we do (read-string "08") it throws an error:</p>
  
  <blockquote>
    <p>NumberFormatException Invalid number: 08  clojure.lang.LispReader.readNumber (LispReader.java:330).</p>
  </blockquote>
  
  <p>Can anyone plese help me to figure out why?"</p>
