Test protected member access lazy loading (ghost objects)

[Ocramius]

Given following code:

class Foo
{
    private $bar;
    protected $baz;
    public $tab;
    public function getBar(self $other) { return $other->bar; }
    public function getBaz(self $other) { return $other->baz; }
    public function getTab(self $other) { return $other->tab; }
}

Any access to these methods, given a non-initialized ghost object, should cause that object to lazy-load.

This should already work, but needs to be tested.
