This revision now requires changes to proceed.
So I read the paper, downloaded this patch, played around with it a little bit,
tried some different tests, like expressions with dependent types,
classes with regular/explicit user-defined conversions, function names and some
other examples that are mentioned in the paper.
It works fine on these.
However, I confirm that the failures in `CXX/except/except.spec/p1.cpp`
detected by the buildbots are real.
It fails for me with this DR, works on parent revision.

I see, yeah agreed.

In general you should respect the formatting tips you get from the non-test
code, as these will fail the pre-merge checks.
But in the test code, our buildbot produces the clang-format patch but this is
not really enforced when merging.
I think what you are doing here, keeping the existing style, is reasonable so
you should disregard this particular tip from the format patch.
The other option would be to format everything in a pre-work NFC commit. This
should be fine for pure semantic tests like these, but you have to be careful
with parser tests.
