And and attempt to increase the visibility of one of its members can be used to make it SEGV. So i don't want more visibility. Also where is the reason? You can read everything just fine and you can overload you exception to print out better formatted output and whatever. The only place where you need to change such member in derived classes is when you are using exceptions as flow control. And duing so is violating exception rule number two. So don't expect this to be changed. >> P.S. - BTW, why not call it IException (or ExceptionInterface) instead of >> Throwable?
