  Every program is a collection of a lot of "short running things". Exceptions work well with this. There's a piece of code that calls some function and expects a result or an error; there's a piece of code much deeper in the stack that can fail. Everything in the middle doesn't care about the failure, except to make sure it doesn't get executed if the failure occurs. Without exception-like mechanism, you have to make the middle care about possible errors, just to prevent code past failure point from executing. Your calls like foo(a) get turned into if(a != error) { foo(a); }, even if it's hidden behind a nice monadic syntax.
