I guess I'm looking for some kind of guidance to generalize this. My understanding is that one only uses exceptions for things which the app finds exceptional, meaning things which it cannot or should not be dealing with, which in some cases may depend on the business practices and policies one is implementing. Recognizing this was a class assignment for the OP, the situation is highly contrived, and the lesson might be how to use and handle exceptions, so great. Do you (or anyone else who'd like to chime in!) have a ... set of heuristics, maybe? .. that help you know when it's appropriate and when it's not? The reason I ask is not merely academic. I see in code many places where it is raising and exception, and then the rescue code does something like this: rescue Exception # blah blah end In other words, they know an exception might be raised, but they trap evey possible exception, rather than a specific one. I'm worried (?)
