Red looks interesting. Though I don't like the mapping of tables to "model". In general, I find that a model should be a consumer of an ORM, not the ORM itself. Otherwise, you expose to much to the business layer and it's harder to refactor.

For example, if you have a column on table A and you later need to move that to table B, a clean model can encapsulate that change. Hard to do when the ORM is being treated directly as the model.
