title: Convert haskell Int with leading zero to String
body: <p>Suppose I have a variable of type Int = 08, how can I convert this to String keeping the leading zero?</p>
  
  <p>For instance:</p>
  
  <pre><code>v :: Int
  v = 08
  
  show v
  </code></pre>
  
  <p>Output: 8</p>
  
  <p>I want the output to be "08".</p>
  
  <p>Is this possible?</p>
