any& operator=(any&& rhs) noexcept;

#
Let VT be decay_­t<T>.
8
#
Constraints: VT is not the same type as any and is_­copy_­constructible_­v<VT> is true.
9
#
Preconditions: VT meets the Cpp17CopyConstructible requirements.
10
#
Effects: Constructs an object tmp of type any that contains an object of type VT direct-initialized with std​::​forward<T>(rhs), and tmp.swap(*this).
