title: Elixir's Range for arithmetic progression
body: <p>Is it possible to express arithmetic progression in a list without listing them all? </p>
  
  <p>In Haskell, you could do it with the range function. </p>
  
  <pre><code>[2,4..10] == [2,4,6,8,10]
  </code></pre>
  
  <p>Is there a similar way to do it with Elixir ?</p>
