title: Rails lists have .first and .second – is there a .hundredth or .sixty_nineth ?
body: <p>Is there a class or other extension for Rails that allows more than the first few elements in a series (and the last)?  These work:</p>
  
  <pre><code>[2,45,2,14,53,23,634,346,34,46,643,634,346,34,34].fifth
  # -&gt; 53
  [2,45,2,14,53,23,634,346,34,46,643,634,346,34,34].last
  # -&gt; 34
  </code></pre>
  
  <p>so where is?</p>
  
  <pre><code>list.sixth
  list.hundredth 
  </code></pre>
