Yeah, *grin*. And on that note, there are times when you will actually
want $foo = &new SomeClass(); versus $foo = new SomeClass(); since
assigning by reference will break any previous references -- something I
forgot to mention to Matthew Weier when he challenged the relevance of
the snippet I sent.
