title: How to use multiple arguments in an if statement with Liquid
body: <p>I want to use an <code>if</code> statement in Liquid with multiple conditionals. Something like:</p>
  
  <pre><code>{% if (include.featured == "true" and product.featured == "true") or (include.featured == "false" and product.featured == "false") %}
  </code></pre>
  
  <p>Multiple conditionals don't seem to work. Have I got the syntax wrong or can Liquid not handle this sort of if statement?</p>
