I don't mind the program bailing out in such a case and telling me where it went wrong, so I can fix the problem. I just don't really see the need for catching exceptions yourself. Especially not in well-tested code, potentially to be compiled. > Exception handling is a boon because almost EVERY expression that you > write can result in a error and checking each one is tedious in the > extreme.

If they don't catch exceptions, the program will bail out, showing what went wrong, yeah? > If you look at the Python C source, you'll notice that probably 50% of > the code is devoted to error handling (that was a guess). That's a lot of error handling.. thanks! mark. -- http://mail.python.org/mailman/listinfo/python-list
