One word: internationalization. Then toString() falls flat on its face.
No. I happen to have some expertise in the area as I've participated to
two large and heavily internationalized systems. i18n has everything to
do with string tables and formatting templates and emphatically nothing
to do with exception hierarchies. The only possible link is that
exceptions should provide the necessary hooks.
They do in that if you want to print a message because of that exception, you
need to print something in the correct language, and that won't work with
toString unless the exception type has built-in internationalization of some
kind - regardless of what that internationalization mechanism might be.
Of course. toString is not a solution to internationalizing exceptions
(or any complex messages).
