work as you are attempting to return the result of an
<emphasis>expression</emphasis>, and not a variable, by reference. You can
only return variables by reference from a function - nothing else.
<constant>E_NOTICE</constant> error is issued since PHP 4.4.0 and PHP
5.1.0 if the code tries to return a dynamic expression or a result of the
<literal>new</literal> operator.
