Unusual notation of passing by reference?
<p>In a legacy php script I found the following line of code:</p>

<pre><code>$CacheLite =&amp; ( "string" );
</code></pre>

<p>Which provokes an error:</p>

<blockquote>
  <p>Parse error: syntax error, unexpected
  '(', expecting T_NEW or T_STRING or
  T_VARIABLE or '$'</p>
</blockquote>

<p>Is it a mistake or a way of passing by reference or something else I don't know. Do I have to enable/disable something in my php configuration in order for this to work?</p>
