By metaskills:

What good is sending methods that you expect your model to respond to (deep in `@proxy.@object`) to the anonymous instance? It has no logic for the attribute. So previous version relying on talking to their models in lazy blocks end up talking to a stupid anonymous class instance with no delegation.
