引用 source

Modern Perl programming, circa 2010, relies on the collected wisdom of the entire Perl ecosystem. It's time to write elegant, reliable, maintainable, well-tested, and predictable code.

另请参阅， the book .而这本书的引述

Modern Perl is a loose description of how experienced and effective Perl 5 programers work. They use language idioms. They take advantage of the CPAN. They're recognizably Perlish, and they show good taste and craftsmanship and a full understanding of Perl.
