Book: Perl 7: A Risk-Benefit Analysis

Dan Book has done adetailed analysis of the Perl 7transition. "Large amount of CPAN modules will not work in Perl7; plans for working around this would either involve every affected CPANauthor, which is a virtual impossibility for the stated 1 year time frame;or the toolchain group, a loose group of people who each maintain variousmodules and systems that are necessary for CPAN to function, who eitherhave not been consulted as of yet or have not revealed their plans relatedto the tools they maintain. Going into this potential problem sufficientlywould be longer than this blog post, but suffice to say that a Perl wherehighly used CPAN modules don't seamlessly work is not Perl."
