Micah Kornfield commented on ARROW-4800:
----------------------------------------
The linked reference seems relatively simple, and returns a reference when
unboxing. I believe this could probably be made more complex to support
move-semantics as well. I've mostly seen usage of this type with either
primitives or unique/shared pointers so the cost hasn't been an issue.
> [C++] Create/port a StatusOr implementation to be able to return a status or
