Deduplication? Cyclical references?

Are there any plans to handle cases where multiple instances of the same object are returned by a query, leading to duplicated content in the responses? How about cyclical references between objects?

I think both cases could be handled by an encoding format similar to Cognitect's Transit, Netflix/Falcor's JSON Graph, or JSON Schema.

It is called **Graph**QL, not TreeQL, after all :)
