Comment:

 another solution while retaining internal pointers is to use a dummy
 variable (since this would duplicate the intrnal pointer , according to
 PHP docs)

 {{{
 $foo=$wp_filter[ $tag ];
 reset( $foo );

 if ( empty($args) )
         $args = func_get_args();

 do {
         foreach( (array) current($foo) as $the_ )
                 if ( !is_null($the_['function']) ){
                         $args[1] = $value;
                         $value = call_user_func_array($the_['function'],
 array_slice($args, 1, (int) $the_['accepted_args']));
                 }

 } while ( next($foo) !== false );
 }}}
