title: Loop through object in nunjucks?
body: <p>I have a file called "list.json" set up like this:</p>
  
  <pre><code>{
    "thing1": "Thing1",
    "thing2": "Thing2",
    "thing3": "Thing3"
  }
  </code></pre>
  
  <p>How can I loop through this? I want to do something like:</p>
  
  <pre><code>{% for item in list%}
    &lt;option&gt;{{ thing }}&lt;/option&gt;
  {% endfor %}
  </code></pre>
