I find that "knowing what's going on" is a very subjective notion in 
programming, usually depending on the language you use. :-)

However, reading the above I still fail to see why you use exceptions in Java 
but not in C++, and why somehow in C++ they prevent you from "knowing what's 
going on".

Actually, I'd never seen it in years until KDE re-enabled it because of 
memory concerns.

Read again : they were implemented in 1992. The standard was voted 5 years 
later.

Please try to be a little more rational about this. Hating a feature is no 
ground for wanting to be banned for everybody else. Exceptions are useful and 
a lot of people happily use them (including me). I certainly hope that in the 
future g++ will have a better implementation and KDE will be able to use them.
