 There's this weird check in do_action():

 {{{
         if ( is_array($arg) && 1 == count($arg) && isset($arg[0]) &&
 is_object($arg[0]) ) // array(&$this)
                 $args[] =& $arg[0];
 }}}

 It was introduced in [4177], probably to fix PHP4 nastiness.

 But, since we're on PHP5 now, the copy-by-reference is not needed anymore.
