Constructs a tagged object.

1) tagged<Base, Tags...> inherits the constructors of Base .
2-4) tagged has defaulted default, copy, and move constructors that invoke the corresponding constructor of Base .
5) Converting move constructor from Base . Initializes the Base subobject with std :: move ( that ) .
6) Converting copy constructor from Base . Initializes the Base subobject with that .
7) Converting move constructor from a different tagged specialization with matching tags. Initializes the Base subobject with static_cast < Other && > ( that ) .
8) Converting copy constructor from a different tagged specialization with matching tags. Initializes the Base subobject with static_cast < const Other & > ( that ) .
