Do you think that it is necessary, given that as a user-level exception, there won't probably exist an enum element corresponding to the error? The only thing would be to add an element USER_GENERATED_EXCEPTION and use that string as the message of "MathUserException". I.e. we should not provide a string argument to construct a "MathUserException". The user will have to unpack the "cause" if he needs access to _his_ message. So, we should probably only provide *one* constructor (with a "Throwable" argument) to make it completely clear that we suggest wrapping any user-specific error into a single type in order to ease communication.
