Agreed. There are certainly times when you want to say "coerce any *string* to an int", and there are times when you want to say "coerce any string to int or None" (maybe you want to take the average of a whole lot of values, ignoring the ones that say "N/A"), but I don't know of any time I want to say "coerce any programming error to int or None", unless you count the exit code of a process. I used the word "improved" rather loosely. ChrisA -- https://mail.python.org/mailman/listinfo/python-list
