title: Rails 3.0.2 Array#join HTML Safe?
body: <p>I have a rails gem that uses a snippet like:</p>
  
  <pre><code>components = []
  components &lt;&lt; label_for(attribute)
  components &lt;&lt; ...
  components &lt;&lt; text_field(attribute)
  return components.join
  </code></pre>
  
  <p>The gem worked fine in Rails 3.0.1, however it escapes (renders as text in a browser) all HTML after updating to Rails 3.0.2. What am I doing something wrong? Thanks.</p>
