+     It is not possible to use overloaded properties in other 
+     language constructs than <function>isset</function>. This 
+     means if <function>empty</function> is called on an overloaded 
+     property, the overloaded method is not called.
+    </para>
+    <para>
+     To workaround that limitation, the overloaded property must 
+     be copied into a local variable in the scope and then be 
+     handed to <function>empty</function>.
