Assigns the contents of that to *this.

1-2) tagged has defaulted copy and move assignment operators that invoke the corresponding assignment operator of Base.
3) Converting move assignment from a different tagged specialization with matching tags. Equivalent to static_cast<Base&>(*this) = static_cast<Other&&>(that);.
4) Converting copy assignment from a different tagged specialization with matching tags. Equivalent to static_cast<Base&>(*this) = static_cast<const Other&>(that);.
5) Assigns that to the Base subobject. Equivalent to static_cast<Base&>(*this) = std::forward<U>(that);

Return value

*this.
