Create a variant object holding the same alternative (if any) held by the specified original. If this variant is allocator‐aware, the specified allocator is used to supply memory. If original is not valueless by exception, the contained value is move‐constructed from the contained value of original. This constructor participates in overload resolution only if all alternatives are move constructible.
