It doesn't look like it, otherwise you'd be aware that the whole point of this submission is that casting return values with
std::movedisables RVO.@lysdexic You claimed otherwise:
"
These std::move invocations are harmless, as they only cast objects to their rvalue reference.
"
If you were right, we wouldn't have the motivation to look at this in EWG.
I am right. Not benefiting from RVO does not mean you're harming anyone.
Again, I recommend you read the submission and also the discussion.
