I did find something demonstrating Moose and DBIx::Class playing together, but the repeated declarations gave me the shudders.
You can take a look at the as-yet-unreleased MooseX::DBIC here which provides a Moose-ish layer over the top of DBIx::Class and (IMO at least) nicely merges the strengths of DBIx::Class with the meta-goodness of Moose. It is not 100% feature complete, there are still some bridging between more obscure DBIC features to be done. But fwiw, this is currently used in a production application and so far so good.
