the manual could do with that tidbit, maybe also the hack for 'getting the
exception out' of __autoload() ...

	function __autoload($class)
	{
		try {
			throw new Exception('foo');
		} catch (Exception $e) {		    		
		    self::handleDebug($e);
		
		    if (!class_exists($class, false))
                 	eval(sprintf('
                     class %1$s
                     {
                         public         function __construct()        { throw new AL_Exception("Class %1$s not found: %2$s"); }
                         public         function __call($m, $a)       { throw new AL_Exception("Class %1$s not found: %2$s"); }
                         public  static function __callStatic($m, $a) { throw new AL_Exception("Class %1$s not found: %2$s"); }
                     }', $class, $e->__toString())); 			
		}
	}

which works best when __autoload() isn't triggered by class_exists("Foo", true)
