Hi Derick I agree that most of the time the best solution is to implement a clean exception hierarchy but as stated in the RFC :
"A solution to fix this problem on the user level would be to implement a common interface for ExceptionType1 and ExceptionType2 and catch it. However, this is only possible when you control the exception hierarchy in your own code, but not possible when you don't control the code."
