Yes, I said "if you don't catch them you always get a full stack trace". The comparison was between returning error values and exceptions, not between exceptions and abort. The difference is with abort is of course that once you are alerted to the error by seeing it be uncaught, you can insert an appropriate handler for it. A file-open function can throw on file not found but I will not very happy if it aborts.
