template< class T > concept movable =     std::is_object_v<T> &&     std::move_constructible<T> &&     std::assignable_from<T&, T> &&     std::swappable<T>;		(since 哋它亢++20)

The concept movable<T> specifies that T is an object type that can be moved (that is, it can be move constructed, move assigned, and lvalues of type T can be swapped).
