There are several functions in WP that return an object by reference.

With PHP5, this is not necessary anymore.

Examples of such functions: get_post(), get_term().

16752.patch as an example. This private function did return by reference, but the callee never received as reference. That's fixed.

The patch additionally shows that it's now possible to call object methods on function returns.
