If we keep the private flag of a property after unset(), we should also keep the type of a property after unset(), e.g.

class test {
        private $z = 42;

        public function __construct() {
                unset($this->z);
        }
}
$a = new test();
$a->z = 21; // fatal: Cannot access private property...

So after unset, $a->z should still have context.

Regards
Thomas
