Redundant code in tests when if improves readability is not too bad. I really like how the new testing code looks. It was a lot easier to follow. Thanks a lot!

IMO we should not disable tests for compilers, only for the reason to be able to use newer language features in the test. Note if the header requires language features I'm fine to disable that for a compiler. In this case we can easily allow clang-17 with a minor change as pointed out in the review.

The patch is getting close to be ready.
