If you've been refactoring during development, and gotten to the point where it is working, clear and maintainable, then there's very little refactoring left to do. I don't think anyone suggests that you refactor code that doesn't need refactoring. Once it is already split into functional pieces, there's no need to continue breaking it up further. -- Steven -- http://mail.python.org/mailman/listinfo/python-list
