Sure, exceptions are bad most of the time. But sometimes they are really useful, like in heavily recursive code, i.e. recursive parsers. Catching exceptions in a single top level function and throwing in every other one makes code much cleaner, since you don't have to propagate and handle errors on every function call and you have single exit point on top level function anyway.
