Class expected

Public Methods

void expected<T, E> ()

Delegate simple operations to the underlying std::variant. std::variant

doesn't set noexcept well, at least for copy ctor/assign, so set it

explicitly. Technically the copy/move assignment operators should also be

deleted if neither T nor E satisfies is_nothrow_move_constructible_v, but

that would require making these operator= methods into template functions.
