title: How do I print out each item in a list of lists in Haskell?
body: <p>I have a list like:</p>
  
  <p><code>
  [[1,2,3,4,5],[6,7,8,9]]
  </code></p>
  
  <p>I'm trying to do it using list comprehension and have got as far as:</p>
  
  <p><code>each_in_lists x = [show y | y &lt;- x]</code></p>
  
  <p>where <code>x</code> is the list of lists.</p>
