your Camel book is out of date, but thankfully, http://www.perldoc.com is not.

If I start using online docs, I'm going to end up wanting to keep every system up to date with the latest perl all the time. I was hoping to avoid that until Perl6 comes out. At present I use systems that have everything ranging from 5.005 through 5.6.1 to 5.8.1, and this has never proven to be a problem, not even when using a lot of modules off of the CPAN. I wouldn't want to start relying on all the latest features; that would be bad design for sure, and not only in terms of OO purity.

In retrospect, my other post seems to have come across as a little harsh. For that I'm sorry. But I disagree that it's bad design to break something that's a fairly new feature anyway, within the same major version (Perl5).
