title: ruby on rails I18 loops
body: <p>I would like to know if it's possible to make a loop for each I18 sub-item.
  Assume I have a .yml file like the following: </p>
  
  <pre><code>subject:
      item1:
         title:
         text:
      item2:
         title:
         text:
      item3:
         title:
         text:
  </code></pre>
  
  <p>What I want to do is something like:</p>
  
  <pre><code>I18.t('subject').each { |item| title = item.title }
  </code></pre>
  
  <p>Is there a way to do it?</p>
