Somehow I managed to forget to test that. Apparently, it does:

ajf@raspberrypi ~/PHP/php-src $ sapi/cli/php -r '$arr = [[1,2],[3,4]]; 
foreach ($arr as list(&$a, $b)) $a = 7; var_dump($arr);'
array(2) {
   [0]=>
   array(2) {
     [0]=>
     int(7)
     [1]=>
     int(2)
   }
   [1]=>
   array(2) {
     [0]=>
     &int(7)
     [1]=>
     int(4)
   }
}

I should probably add a test for this.
