alt Hacker NewsSorry, I had some other thread that involved destructors in my head.
But the point is `defer` is still in "spooky action at a distance" category that I generally don't want in programming languages, especially in c.

Agree, this is also why I'm a bit weary of it.
What brings me on the "pro" side is that, defer or not defer, there will need to be some kind of cleanup anyway. It's just a matter of where it is declared, and close to the acquisition is arguably better.
The caveat IMHO is that if a codebase is not consistent in its use, it could be worst.
But the real-world alternatives that people use are:
1. goto, which is "spooky action at a distance" to the nth degree. It's not even safe, you can goto anywhere, even out of scope.
2. cleanup attributes, which are not standard.
