Re^3: Object Persistence, Moose and playing nicely with ActiveRecord

[Corion]

I'm not aware of any Perl-ORM implementing Single Table Inheritance (or rather, Single Table Object Storage). I guess you can fake this by creating updateable views for all classes if your underlying DB supports that.

For composition, I think DBIx::Class (like Class::DBI) has inflation/deflation links which can be used to instantiate the appropriate objects for fields. But I haven't used either.
