I'd suggest QUniquePointer. Honestly, I don't think we have too many alternatives here. We can try Rust-like naming (something like QBox), but it just looks weird and tells nothing about ownership semantics.

After that we can write "using QScopedPointer = QUniquePointer" for people who get used to old scoped pointer and want to highlight the fact that a resource will be released at the end of the scope. But personally I think we don't need to have one more entity without a real reason to do that.

    What would you then name a Qt counterpart of std::unique_ptr, considering that
    QScopedPointer is not such a counterpart?
