Go doesn't have RAII or destructors, it has defer.

  Which definitely does weird things in a loop.

    IIFEs trivially solve that. tbh I see FAR more range-var-misuse with Go loops than defers. I've seen over 100 range-var problems, and seen lints catch many more (several thousand), but I've only seen a loop defer issue once. When a defer is needed, it seems like people both remember the issue better (`defer` is a new construct for many, `for` is not and habits from other languages can mislead them), and the code is complex enough to justify a helper func, where a defer is trivially correct.

  defer proposal for C made in 2021 https://www.open-std.org/jtc1/sc22/wg14/www/docs/n2895.htm https://www.open-std.org/jtc1/sc22/wg14/www/docs/n2895.htm ... why isn't this in C already?

    You must be new here. They’ll consider adding it in late-mid-‘40s.

    In reality, it is already in every compiler that matters. For some reason, they don't want to put it in the standard.
