    Description

      See epic for more information.

      We're asking all maintainers to execute the following programme:

      For each pair of types that are comparable:

      • add private
        • equals() as a back-end for == and
        • compare() as a back-end for <=> that can be out-of-line (cf. QTBUG-100276)
      • a classification (incl. user docs! (QTBUG-104110)) into exactly one of
        • strong
        • partial
        • weak
      • add tests for all relational operators (QTBUG-104108)
      • all traditional relational operators (==, !=, <, >, <=, >=) that work in C++20 (incl. synthesized ones) should also work in C++17.

      Explore how much of this we can hide behind macros, and define such macros.
