title: Function as array value
body: <p>I can't seem to find anything of this, and was wondering if it's possible to store a function or function reference as a value for an array element. For e.g. </p>
  
  <pre><code>array("someFunc" =&gt; &amp;x(), "anotherFunc" =&gt; $this-&gt;anotherFunc())
  </code></pre>
  
  <p>Thanks!</p>
