Personally, I don't understand the need for exceptions at all. 
Usually, only a calling context can fix the error and continue 
execution of the program. If exception caught by a top level 
handler, all it can do is just a crash. Moreover, with 
exceptions, you need to wrap every piece of code with ugly 
"try/catch". A plain check of the return code is much better. 
Sometimes you can't return something adequate (when an index is 
out of range or container is empty). These cases are programmer's 
errors and assert is more than enough.
