I can feel with you - it's much work to upgrade the modules, or to do fresh installs with the new Perl version.

To avoid that pain in future (both for you and others), I'd like to encourage you to test release candidates of stable perl versions before the final one hits the CPAN, and report any bugs you find, and any trouble you have with the new perl versions.

Only with feedback from users can the perl developers release stable, mature and backwards compatible versions of perl. Don't think somebody else does that already - there are people, but they have different configurations and different code bases. So your feedback counts.

Also things that nobody tests might go away - as happened to suidperl.
