Hi,

I'm evaluating Scala and Lift for a new project and in reading through
the "Getting Started" guide, I noticed that the ORM approach in Lift
seems to involve weaving persistence code directly into the entity
classes (LongKeyedMapper, MappedLongForeignKey, etc.) and companion
objects. It's an interesting design choice because the trend in other
frameworks is toward an intentional separation of concerns: POJOs as
entities, DAOs for persistence. Spring and Seam with Hibernate/JPA
come to mind. Could someone explain the reasoning behind Lift's take?
I don't mean to pass judgment, just trying to understand the
motivation.

Thanks.
-Rob
