O'Reilly haven't announced "Perl: The Good Parts", but it's a book that's crying out to be written....
O'Reilly's not going to do that book, but Piers is right -- it's a book that needs writing. I've used Perl for over a decade. I've asked and answered questions on Perl Monks since its inception (as the second user to register for the site). I know a little bit about project management, a little bit about testing, and a little bit about working on projects in a team composed of developers with divergent skills and interests -- even some about mentoring.
I also know a little bit about writing, editing, and publishing books.
I'm looking for feedback on the idea now. Would you be interested in buying, reading, promoting, reviewing and offering feedback on, and/or handing out a book called "Modern Perl" which teaches the language and the principles behind the language so that you can take advantage of the good parts, ignore the bad parts, and ameliorate the awful parts? Would you read or comment on a similarly themed weblog in conjunction with the book?
Of course it will cover some of the best modern CPAN modules.
If you're interested, please feel free to reply here, to my email (chromatic at wgz dot org), or even @chromatic on identi.ca.
Update: dmp2k suggested that the name "Modern Perl" is better than "Maintainable Perl". I agree. Do you?
