I think there's a typo in the last line of the post. Should it be V8 13.4 instead of V8 13.8?

I think it's accurate when interpreted as "unflagged by default" for arcane reasons.

Very nice! We’ve been using this in a lot of our tests to help perform cleanup of fixtures and the like. I just wish there was somehow better support in Typescript or Eslint to ensure one doesn’t forget to use “using” instead of “const” when getting a disposable. Not straightforward to do though.
