For example, here, you changed the pretty printer test, but we still run that test with Clang 12 and Clang 13, not only with Clang `main`. Since older Clangs don't contain your change, the test fails (and rightfully so). I'll add the necessary `XFAIL`s, but please look out for these breakages since they are somewhat disruptive. Thanks!

Thanks for the context/fix - I'll try to keep it in mind.
