I object to your "exceptions" pragma.

Do you object to the whole idea, or just the name? The idea is nothing new, we're doing exactly the same thing as Fatal, but on a lexical scope. In other words, open() is simply turned into open() or die under the hood. If you think that Fatal is a good idea, but this pragma is a bad one, then I'm very interested in hearing more of your reasons why. My biggest problem with Fatal was always that it had too wide a scope.

As per BrowserUk's suggestion, I've renamed the pragma to lethal, avoiding the confusion that a statement like no exceptions may cause. no lethal simple disables the effects of the lethal pragma. Things can still throw exceptions, our pragma just won't have been the cause of them.

I hope this solves your objection to the name; if it doesn't, then I've misunderstood your node, and I'd love you to elaborate.
