The Java AutoCloseable seems like a cleaner version of the MS __try/__finally: try (MyCloseable c = useSomething()) { // stuff } Why isn't this the path explored? The main difference would be not having extra nested blocks. That seems relatively minor, no? It can be improved arg list: try (MyCloseable c1 = useSomething(), ElseThing c2 = elseThing()) { // stuff }

This syntax relies on destructors, which C doesn't have.

  One could pass in a cleanup function that will be called - but this is very similar to gcc’s cleanup attribute.

  The Java implementation doesn't use destructors. The AutoCloseable interface only has the one close() method, so for C a callable function would do.
