alt Hacker NewsI don't understand why destructors enter the discussion. This is C, there is no destructors. Are you comparing "adding destructors to C" vs "adding defer to C"?
The former would be bring so much in C that it wouldn't be C anymore.
And if your point is "you should switch to C++ to get destructors", then it seems out of topic. By very definition, if we're talking about language X and your answer is "switch to Y", this is an entirely different subject, of very few interest to people programming in X.
Sorry, 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.
