    Description

      The comparison operators in containers are heavily constrained on the contained types + they use conditional noexcept.
      This will most probably cause issues with the comparison helper macros, because they are not designed for a proper support of templates and constraints.

      The scope of this task is to investigate what needs to be done with the comparison helper macros, and provide the needed improvements.
