Proposal: Automatic Resource Management

[Bob Lee]

Neal, it might help if you cited some specific examples. I've never
personally suffered from Closeable's exception signature, and I can't
imagine suffering from that of Disposable. I have suffered from the fact
that no one seems to close resources correctly, and I'd love to have this
feature whether we get closures one day or not.
