title: Pass the result of a Velocimacro into another Velocimacro
body: <p>I have a few Velocity Macros (Velocimacros) I am using in some of my templates; I would like to pass the results of say a date format macro into another that pads string values. I am trying the following: </p>
  
  <pre><code>#pad(#dateFormat("my date"), 30)
  </code></pre>
  
  <p>I am getting an exception saying, "Invalid arg #0 in VM #pad..."</p>
  
  <p>Is it not possible to pass the results of a macro into another macro? I tried to set the value of the "#dateFormat" macro into a variable using: </p>
  
  <pre><code>#set ($myParam = #dateFormat("my date"))
  </code></pre>
  
  <p>however, I am getting another exception.</p>
  
  <p>Thanks.</p>
