title: Robot Framework accessing a keyword from test suite Metadata
body: <p>I want to set for each test inside the test suite a simple report of the computer name,
  So I've created the following simple robot <code>__init__.robot</code> file:</p>
  
  <pre><code>*** Settings ***
  Metadata        Executed At    Get Environment Variable   COMPUTERNAME
  Library         OperatingSystem
  </code></pre>
  
  <p>The problem is that the <code>Get Environment Variable</code> is translated as a string instead of calling the keyword <code>Get Environment Variable</code> with the argument <code>COMPUTERNAME</code></p>
  
  <p>The log put is:
  <code>Executed At:   Get Environment Variable COMPUTERNAME</code></p>
  
  <p><strong>Question:</strong>
  How can i call some keyword from the settings <code>Metadata</code>?</p>
