Is perl6 production ready?
Yes, but please use its new name, Raku. Note new releases come out monthly so you shouldn't use the Debian packages since they are way behind. We have a member on the release team who provides Debian packages as "rakudo-pkg" so apt/aptitude update/upgrade work as expected.
And the community is smart, friendly, and welcoming. Check IRC channel #raku.
Blessings,
