All of which is just wrappers against already available perl modules so
what are we gaining?

Although I have not worked with Catalyst I have reviewed it quite a bit
because I was considering it against other options.

I was walking through the tutorial and everything looked fairly
reasonable until:

 # load from multiple namespaces.
        MyAppDB => [qw/Book BookAuthor Author/]


# has_many():
    #   args:
    #     1) Name of relationship, DBIC will create accessor with this name
    #     2) Name of the model class referenced by this relationship
    #     3) Column name in *foreign* table
    __PACKAGE__->has_many(book_authors => 'MyAppDB::BookAuthor', 'book_id');

Which is ugly, beyond ugly and I am not interested any longer.

I fully understand your theory on frameworks. I use Django for a lot of
work. That being said... Frameworks are great when you need a kitchen
sink, fridge, floors and cabinets.

We just need the fridge.
