I agree on the use of RTTI; I don't think there are many cases
you really need it.
But for exceptions, I think it is a very elegant error handling
way. If the libraries have a good error handling mechanism 
themselves, they indeed don't need exceptions. But I think for
applications exceptions are a very practical way to handle errors.
[I won't repeat Bjarnes arguments for exceptions here]. 
In short; RTTI should be depreciated, but exceptions not. They should
just not be used in libraries.
