Just because it is movable doesn't mean you move the object itself, a move moves the content of the object. So each move triggers a move of the payload of a scoped pointer to another scoped pointer in another scope.I never understood why anyone would think the name would make that impossible.The counter argument is: it would imply that the _pointer_ escapes the _scope_.Not the smart pointer, it never leaves. Only the raw pointer does, and only because you have moved it out of the scoped pointer, and it into a new one.
<devil's advocate>This isn't a counter argument -- in a shared pointer, you share the _pointer_, not the smart pointer itself (you'll have several distinct smart pointer objects, but all sharing the same pointer).
In a scoped pointer, you "scope" the pointer, not the smart pointer object. :-P
This conversation is 9 years too old -- the ship has sailed. std::unique_ptr is the vocabulary type that is on every C++ book teaches, every C++ talk explains, every C++ project uses (all over the place inside Qt itself). Unless some extraordinary argument appears, that's the name that Qt should also use.It is still a terrible name. Unique pointer refers to something std::unique_ptr can abstractly achieve, but not what it actually is.
With this I may agree. The mental exercise used here is not that the pointer itself is "unique" (whatever that means), but the ownership is unique -- and represented by the unique_ptr object itself.
