TIL: all code posted for review on https://codereview.stackexchange.com/ has to be compilable.

I noted that a function wasn't available in the snippet in my post, but 2 users still voted to remove the question without any feedback, person-to-person communication, etc., because it broke the rules.

While I'm a rule-breaker, and the problem, maybe GPT4 is where to go for code reviews.
