title: Assigning a variable within a statement in liquid
body: <p>Is there a way to have a variable within a statement in liquid so that something like the following:</p>
  
  <pre><code>{% assign somevar = 'about-us' %}
  {{ pages.somevar.content }}
  </code></pre>
  
  <p>would result in the same output as if you had originally used:</p>
  
  <pre><code>{{ pages.about-us.content }}
  </code></pre>
