title: get value of the string stored in a variable, whose name stored as string in another variable
body: <pre><code>&lt;#assign blah = "foo"&gt;
  &lt;#assign foo = "awesome"&gt;
  </code></pre>
  
  <p>Can we render "awesome" without referencing foo ?</p>
  
  <p>I tried something like <code>${${blah}}</code></p>
  
  <p>But it isn't working, any ideas ?</p>
