*If* we're going to create syntax for anonymous blocks, I think the primary use case ought to be cleanup operations to replace try/finally blocks for locking and similar things. I'd love to have syntactical support so I can write

instead of
myLock.acquire() try: code code code finally: myLock.release()
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. @acquire(myLock): code code code -Barry
