Sounds doable and sounds like what our AOT had in mind. cc @bigopon

To fully support type check in template, we need to parse binding scopes (if/repeat/with create new child scope), this is different than JavaScript variable scope. Also our scope has a chain of parentContext and overrideContext, which is similar but not same as JS's prototype chain.
