Antoine Pitrou commented on ARROW-4800:
---------------------------------------
What is the cost of unboxing the value with such a scheme? Say I have a
{{StatusOr<std::vector<something>>}}, can we avoid copying the vector when
getting its value?
> [C++] Create/port a StatusOr implementation to be able to return a status or
> a type
