Hi Dmitry,

i threw this only in empty room to start a discussion and create the 
"idea". I would like to hear the idea for exceptions in core generally. 
Throwing exceptions is one thing, reacting on exceptions is the next.

So the question is, should there be implemented a general exception 
class in core for reactions, are there existing prototypes a.s.o.

The line i found would be kind of completition to include Errors and 
Notices from php, may be for analysis or still as a pipe to react at a 
central point.
