Okay, this is useful. Thank you for straightening out my mental model.
It makes sense to define strings as just naturally Unicode... and
anything else is in some ways not really a string, although it's
something that might have many of the same methods. I guess this
mental model is being implemented more thoroughly in Py3K... Anyhow,
it makes sense.

I'm still puzzled why I'm getting some non-Unicode out of an
ElementTree's text, though.
