Indeed, it would be very cool to have these kind of (dare I say) block
decorators for managing resources. The really nice thing about that is
when I have to protect multiple resources in a safe, but clean way
inside a single block. Too many nested try/finally's cause you to
either get sloppy, or really ugly (or both!).
RSMotD (random stupid musing of the day): so I wonder if the decorator
syntax couldn't be extended for this kind of thing.
