Is there a scheme for Python developer to use so that they are safe from incorrect mixing?
Put the following:
import sys sys.setdefaultencoding("undefined")
in a file named sitecustomize.py somewhere in your Python path and Python will complain whenever there's an implicit conversion between str and unicode.

That helps! Running unit test caught quite a few potential problems (as well as a lot of safe of ASCII string promotion).
