Original:
Specifies that an instance of the type can be move-constructed (moved). This means that type has move semantics: that is, can transfer its internal state to a new instance of the same type potentially minimizing the overhead.

is unspecified after the move. However, it must still be valid, that is, no invariants of the type are broken.
