Do you X? Sure, why not? I am not suggesting anything even vaguely like what you are saying. The compiler should emit whatever the code it sees says to emit.

Do you X? Sure, why not? I am not suggesting anything even vaguely like what you are saying. The compiler should emit whatever the code it sees says to emit. If it neglects to arrange to close TCP connections, they won't be closed. So what? I am not interested in TCP connections right now, or I would patch up that bit, in response to the warning the compiler spit out. I have other things to worry about right then. The release build will insist everything be taken care of, so there is no "other language". You are just permitted to get there by a route you choose, in place the route Cargo would impose now.
