Defer TS is now out with Clang 22.1.0.

Read about the changes in Clang here: https://releases.llvm.org/22.1.0/tools/clang/docs/ReleaseNotes.html#id6

Just need to wait for an official cut of the GCC to have defer out and then I can consider the job done.

So far, so good.

I saw someone criticize defer as "spooky action at a distance", which is a clever physics quote, but I disagree; pragmatically it seems great.
