Handel? Well there's your problem... :-)

I'd love to write about how I've done things in Mango...if I only could
make myself have the time to do it. To be honest, the
outside-core-as-model didn't really become really clear to me until I
stuffed Handel::Cart into Mango as a Catalyst Model.

The best approach for me has been what mst has said before. Make your
core stuff usable outside of the work of Catalyst. Seems like a no
brainer, but when you're just learning Cat and following examples, it's
easy to forget.

For a quick example of how it's done in Mango:

	Handel::Cart - seperate app that does cart magic
	Mango::Provider::Carts - responsible for cart CRUD API in Mango
	Mango::Catalyst::Model::Carts - wraps above in Model instance
	MyApp::Model::Carts (isa Mango::Catalyst::Model::Carts)

For non-Handel things in Mango...it's just the last ones:

	Mango::Provider::Users - responsible for user CRUD API in Mango
	Mango::Catalyst::Model::Users - wraps above in Model instance
	MyApp::Model::Users (isa Mango::Catalyst::Model::Users)

The main theme being...the models are just DB thingies...they're
completely usable outside core classes (domains/business logic, etc)...
