    Description

      See epic for the big picture and (the latest version of) QTBUG-104113 for a detailed description of the necessary changes.

      QVariant is special in that we used to have op< et al, but, since variants of different type may not be comparable, or contained types may not be ordered, we removed it again. C++20 std::partial_order would allow to bring this back, and report QVariant(QRect()) <=> QVariant("hello") as unordered.

      Discuss and implement.
