Throwable class design

[rumbu]

Ok, maybe my thoughts are polluted by some C# programming 
practices, but I learnt that exceptions are never intended for 
the end user (one of the reasons is that the exception mesages 
are in most cases displayed in english language). In Windows 
world, throwing an exception displays a message with a nice two 
buttons: Close and Debug. This will make the accountant using my 
software very eager to click on Debug :)

My way to deal now with *unattended* exceptions is to log them 
for further investigation, but I will never display a raw 
exception message, considering the fact that my LOB applications 
are in most cases multilanguage.
