title: How to refer to a field that starts with a digit in dust.js?
body: <p>I've got a JSON structure like this and want to refer to the 64x64 image in a dust template. This doesn't work because of the 64x64.</p>
  
  <pre><code>   "images": [
          {
              "dateLastUpdated": "2014-02-24T23:00:00Z",
              "links": {
                  "1024x1024": "http://imghost/some.JPG",
                  "147x147": "http://imghost/some.JPG",
                  "358x358": "http://imghost/some.JPG",
                  "498x498": "http://imghost/some.JPG",
                  "64x64": "http://imghost/some.JPG",
                  "726x726": "http://imghost/some.JPG"
              },
              "status": "OK"
          }
      ],
  </code></pre>
  
  <p>This is the dust.js template</p>
  
  <pre><code>{#users}
  &lt;tr&gt;
    &lt;td&gt;&lt;img class="thumb" src="{.images[0].links['64x64']}"/&gt;&lt;/td&gt;
    &lt;td&gt;{.title}&lt;/td&gt;
  &lt;/tr&gt;
  {/users}
  </code></pre>
  
  <p>I've tried </p>
  
  <pre><code>{.images[0].links.64x64}
  {.images[0].links['64x64']}
  {.images[0].links.'64x64'}
  {'.images[0].links.64x64'}
  </code></pre>
  
  <p>How do I do this?</p>
  
  <p><strong>Update 1</strong></p>
  
  <p>I've found a workaround which solves this specific problem but not the general one. If I would want to refer to different sizes in the loop I would have the same problem again. </p>
  
  <pre><code>{#users $size="64x64"}
  &lt;tr&gt;
    &lt;td&gt;&lt;img class="thumb" src="{.images[0].links[$size]}"/&gt;&lt;/td&gt;
    &lt;td&gt;{.title}&lt;/td&gt;
  &lt;/tr&gt;
  {/users}
  </code></pre>
  
  <p><strong>Update 2</strong> </p>
  
  <p>Should have mentioned the dust.js template in the question :)</p>
