>
> While reviewing test coverage for FLINK-4705 I have come across that
> {{Either}} only implements partial object reuse (when from and to are both
> {{Right}}). We can implement full object reuse if {{Left}} stores a reference
> to a {{Right}} and {{Right}} to a {{Left}}. These references will be
> {{private}} and will remain {{null}} until set by {{EitherSerializer}} when
> copying or deserializing with object reuse.
