This is the best conceptual definition of what `std::move` is. I feel that is how every book should explain these concepts in C++ because its not a trivial language to get into for programmers who have worked with differently opiniated languages like python and java.
If you read Effective Modern C++ right Item 23 on this, it takes quite a bit to figure out what its really for.
