title: Array with range values?
body: <pre><code>a = [1, 2, 3..9, 10, 15, 20..43]
  print a.include?(5) # Returns false
  </code></pre>
  
  <p>I was expecting it to return <code>true</code>, but <code>3..9</code> is not translated to <code>[3,4,5,6,7,8,9]</code>. </p>
  
  <p>I am missing something silly but I can't figure it out. Basically I want to initialize it with both regular fixnums and ranges.</p>
