title: Why doesn't Clojure let me define zero-padded numbers?

  </code></pre>
  
  <p>This yields <code>Exception in thread "main" java.lang.NumberFormatException: Invalid number: 08 (11.clj:1)</code>. Why can't I do this in Clojure? Are there any workarounds?</p>

  <p><strong>Clarification</strong></p>
  
  <p>All I want to do is paste this grid somewhere and have it act as if there were no leading zeros, even if it takes a little coercion. I don't want to have to drop all of the zeros in my editor, I'd just like to paste it in there and have each number behave as if there were no leading zeros.</p>

  <p><strong>One other strange detail</strong></p>
  
  <p>The REPL seems to allow zero-padded numbers, but executing a <code>.clj</code> file with <code>java -cp clojure.jar -i some_file.clj</code> will throw the error.</p>
