Wouldn't it be possible to add some kind of @json class annotation then, which cannot be combined with "extends" and dynamic types? I understand that serialization of inheritance trees and arbitrary data is a complicated problem. So why not allow a simple case first and continue from there? I guess inbuilt json serialization of simple types would already cover alot of real world rest scenarios which most users care about.
