So this is more akin to panics, where you don't really care about handling the error but rather want to stop dead in the tracks. But take something like .NET's SocketException, which contains a SocketErrorCode property; you may very well want to take different action depending on the type of error this is. This may be as simple as changing the text of the error shown to user (with suggestions on how to fix), but could also be some code based recovery that takes different action depending on the type.
