Rvalue reference overloads for optional

by Andrzej Krzemieński

Excerpt:

... optional is just missing the rvalue reference overloads for these functions. This is what this proposal intends to fix: add rvalue reference overloads for member functions value and operator* (not for operator->, because it appears not to be implementable). I consider it a bug fix rather than a new feature, primarily because such an overload already exists and has been approved for function value_or. This is why I propose to fix it still in the first version of Fundamentals TS.
