----------------
`static` not needed here, remove. I don't think LLVM guidelines enforce strict
const correctness either so the `const` could be removed as well if wanted.

Sounds good, just want to make sure it's something we see value in fixing (as
opposed to just being "churn"). I'm happy to put up an NFC patch for that!

I disagree, just because the code "compiles" it doesn't mean it's good. The
only time I've seen code like this is in [[ https://www.ioccc.org/ | obfuscated
code competitions ]] :)
We should not force the user to run clang-format to fix this - clang-tidy
should preserve the existing space. This is not a matter of style either, it's
a de-facto way of writting C++ (and many other languages): variable types and
variable names in a declaration are separated by a space.
