Proposal: Automatic Resource Management (original) (raw)

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.

I think you're missing the point, Josh. People do this today with Closeable, because that's the closest interface available that could be used to perform this function, but clients suffer from its exception signature. Disposable is better in one way - it would be retrofitted onto more classes - but much worse in its exception signature. You're saying that there's no pain because you can't use it as a parameter type. I'm saying that is the cause of the pain. The language construct that you're proposing does not supplant this technique of resource management, but the APIs you're proposing to go with it interfere with the technique.
