  Does this mean that before this patch

    foreach ($arr as $val) {}

  did not put a reference in $val but a copy (clone)?
A copy, yes.  Using 'clone' here is a bit misleading though, it didn't call 
__clone or anything.  For objects under PHP 5, this doesn't make too much 
of a difference. For everything else, it does.
