Review comment:
> Ur, do we handle this in complex types like Array/Map/Struct? The
current AS-IS PR seems to handle only the top-level string type. If we don't
support complex types, we need to narrow down more specific about the benefit.
Yea, nice catch. I'll check if we can support the suggested case. Thanks!
