Thanks to the CPAN testers, I have found out that there is an exciting bug in version.pm. Somewhere in between versions 0.74 and 0.82, qv()'s behaviour changed, and so my CPAN::ParseDistribution started failing two of its tests.

There's no reason to ever use version.pm, which only exists to support the absurd practice of using things other than number as version numbers. Use of version.pm makes tools for dealing with the CPAN an order of magnitude more complex.

USE OF version.pm IS A BUG. STOPPIT!
