But if you look in Fido, page 5 or so, you'll notice there's a similar line in a list of examples, that says:

So now the "new Camel" is Amelia, and then it was Fido. We are interested in the Camel, not in the scalar variable that holds a reference to it...

And, well, a lot has changed (in the book, if not in Perl), for example, I heard that the chapter about regular expressions is new and very good (and probably written by Jon).
