Betreff: Re: [PHP-DEV] [RFC] Magic Method that handles unset($object)
You could use references, you would have to move some code
around, though.
I'm not sure that's exactly what you want, but give it a shot:
...
$parent = &setup();
$parent = null;
This happens to work in this case because when you assign null to $parent you break the reference circle in the parent/child-relationship "by the way" because you work with references. It's not a general solution, though.
