your Camel book is out of date, but thankfully, http://www.perldoc.com is not.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