Have to agree with chromatic, at least with the negative tone re: Modern Perl and BioPerl. As I mentioned elsewhere, I would really appreciate anything constructive from the BioPerl end, something beyond 'it sucks and it needs to be rewritten'. Seeing as BioPerl is pretty much being developed by a handful of developers who have other full-time jobs (myself, Lincoln, Jason, Dave Messina), not to mention the code base is huge and is used in a large number of other distributions (both CPAN and DarkPAN), it's kind of hard to dedicate ourselves to starting from scratch, even though we have started something along that path using Moose.
