title: Ant flaka: declare variable with dynamic name
body: <p>I'm using ant with flaka.</p>
  
  <p><strong>How can I declare a variable with dynamic name (retrieved from another variable)?</strong></p>
  
  <p>I would like to do something like that:</p>
  
  <pre><code>&lt;fl:let&gt;
      #{varname} = value
  &lt;/fl:let&gt;
  </code></pre>
  
  <p>however, i think it's illegal.</p>
  
  <p>How can i do that?</p>
  
  <p><em>thanks!</em></p>
