Once it's on the stack, the GC can see it for the full run of `main`. This is why this case is different.Note that Java is even more aggressive, and might *still* collect it, because it could legitimately set `stopper` to null after the last use to signify that it's no longer needed.
And it follows that programming in GC-supporting languages *may* be harder than in languages with manual memory management, right?
