Sure you can! Frankly, I would much prefer throwing an exception than 
the present form of "user specifialble callback".

However, I am very curious about the overhead incurred by compiling CLN 
without -fno-exceptions. If that really turns out to be negligible, I am 
all for throwing exceptions as that is so much more convenient. I 
suggest to start looking for the destructor overhead.

Best wishes
