title: Get to list item which called by symbols or marked with $ sign
body: <p>I use jsondiff.</p>
  <p>I have next dict:
  <code>&lt;class 'dict'&gt;: {'id': 1111, delete: ['longcode']}</code></p>

  <p><code>delete</code> is not symbolic. When I try to get it by name, I have KeyError exception. But it presence. Idea is by using jsondiff get difference between json objects. And want to remove or separate <code>delete</code> list from dict</p>
