title: Pass an include parameter inside a liquid call
body: <p>I have a page say index.html and a file with liquid code called <code>tags</code>. I want to pass a parameter which I specify in index.html to a liquid call in <code>tags</code>. Namely,</p>
  
  <p><strong>index.html</strong></p>
  
  <pre><code>&lt;div&gt;
    {% include tags param="site.categories" %}
  &lt;/div&gt;
  </code></pre>
  
  <p><strong>Tags</strong></p>
  
  <pre><code>{% assign tags_list = {{ include.param }} %}
  ...
  </code></pre>
  
  <p>The <code>{% assign tags_list = {{ include.param }} %}</code> does not work for some reason. Is it possible to do so because this allows me to use <code>tags</code> file for multiple purposes? Instead of writing liquid calls in every page Iwould be able to just do <code>{% include tags param="something" %}</code>. Thanks.</p>
