"WebSo, don't think, "Move Semantics", means that the bytes of the type are moving or being copied in memory; rather, realize it refers to movement of ownership of those bytes. As part of the ownership moving, the bytes may or may not be copied from one location in memory to another, but, that depends on needs and optimizations. " - Bitwise copy semantics
