Where did this come from? Nobody was debating that. In the event that
you really meant object, you are wrong, as per http://php.net/foreach,
object iteration was added in PHP5.

I am in no way seeing how this would break forwards compatability.
Anyone who wants to submit a patch that iterates over an object can
easily do so, leaving out the typecast (maybe even making a comment
that it is an object so that nobody else comes along and tries to
typecast it), and continue along with their life.
We cannot change the behavior of foreach to force the typecast, but we
can however typecast wherever we know we are expecting an array.
