    Description

      QtConcurrent currently takes its container argument as reference or const reference:

      QFuture<void> QtConcurrent::map(Sequence &sequence, MapFunctor function)

      It would be better to take an universal reference instead

      QFuture<void> QtConcurrent::map(Sequence &&sequence, MapFunctor function)

      This would allow some additional use cases when working with temporary container adaptors:

      QtConcurrent::map(db->range<XId, XMail, XPassword, XSalt>(), functor);
