++ for this.
Remark: I think it's still better to pass $originalThis to __clone() as a
regular
object with no lifted access restrictions to private/protected members (i.e.
just
pass it as regular fcall argument).

Description:
------------
When you clone an object the __clone method does not have a way to get a
reference to the original object.
It would be advantageous to have a way to get the original object from within
the __clone method.
One reason for this is that you can have an object that has child objects that
in-turn reference back to the parent object and on clone you want to clone
these child objects but would need to remove the original reference and replace
it with the new parent reference.
This feature could be implemented by simply passing the original object as an
argument to the __clone() method.
Reproduce code:
---------------
class Parent
{
protected $children = array();
public function __clone($originalThis)
{
$clonedChildren = array();
foreach($this->children as $child)
{
$childClone = clone $child;
$childClone->attach($this);
// we have no way of getting the original
// object do we cant do the following...
$childClone->detach($originalThis);
}
$this->children = $clonedChildren;
}
}
Expected result:
----------------
N/A
Actual result:
--------------
N/A
