Is there (currently) a difference between
	foreach ($obj ...)
and
	foreach (get_object_vars($obj) ...)?

If there is then the migration is not always "extremely" simple, no?
If there isn't then we can simply define that from now on the former is =
equivalent to the second one and ignore future changes to visibility, =
hooks etc.

My main point is that over the last years a lot of (for our code =
unnecessary) complexity was added but I hardly complained because other =
people have other needs. I just ask for similar consideration in return =
when stripping stuff.
