I've structured this into a series of commits for even easier reviewing, if that helps. I could easily split this up into separate PRs if desired, but as this is low-risk with simple edits, I thought one PR would be easiest. * Drop unnecessary semicolons after function definitions. * Cleanup comment typos. * Cleanup `static_assert` typos. * Cleanup test code typos. + There should be no functional changes, assuming I've changed all occurrences. * ~~Fix massive test code typos.~~ + This was a real problem, but needed more surgery. I reverted those changes here, and @philnik777 is fixing this properly with #73444. * clang-formatting as requested by the CI.
