title: Rails / HAML: image_tag inside a link_to helper
body: <p>How do I write this in HAML?</p>
  
  <pre><code>&lt;a class="pull-left" href="#"&gt;
    &lt;img class="media-object" data-src="holder.js/64x64"&gt;
  &lt;/a&gt;
  </code></pre>
  
  <p>I tried this but it failed:</p>
  
  <pre><code>=link_to "#", :class =&gt; "pull-left
   =image_tag "64x64.gif", :class =&gt; "media-object"
  </code></pre>
