This is intentional behaviour, there are times when you want a copy of a
reference and there are times when you want a reference to a reference.
For instance consider the following:
$foo1 = $foo2 = $foo3 = new a();
$foo2 = new b();
If these were references to referen

Yeah, *grin*. And on that note, there are times when you will actually

There's a difference between a reference to a reference and a copy of a
reference *hehehe*.
