i would describe python3 and perl6 at almost exactly the same place in their development cycles. python3 may be "released" and blessed, its adoption is only tentative...everyone is in the same boat, they want to be part of the future, but the tool isn't done yet and certainly everything else in module-land is a long way from catching up.
afaik python mysql support isn't even on 2.6 yet...getting to 3.0 is going to be a while
