Bug description:  Magic __parent property (or method)

Description:
------------
When writing code with complex object structures I often need a reference
to the parent object. Let's say we have an object "parent" that has a
property which is an object "child":


class parentClass {

  var $child;
  var $dummyVar;

  function __construct() {
    $this->child = new childClass($this);
    $this->dummyVar = 'hello';
  }

}

class childClass {

  var $parent;

  function __construct($parent) {
    $this->parent = $parent;
    echo $this->parent->dummyVar;
  }

}

$example = new parentClass;

// prints: hello


I very often need to create my code like this because I very often need to
be able to have a reference to the parent object of an object. 

Shouldn't PHP have such a reference by default? There could always be a
Magic reference like:

$myParent = $this->__parent;

Or maybe a Magic method:

$myParent = $this->__parent();

This would then always return the parent object or eventually reach the
main script scope.
