By not inheriting from unicode, the bug can be fixed while retaining a class implementation (see sandbox\curry292.py for an example).

But, be clear, it is a bug. If all the inputs are strings, Unicode should not magically appear. See all the other string methods as an example.

But the Template classes aren't string methods, so I don't think the analogy is quite right. Because the template string itself is by definition a Unicode, it actually makes more sense that everything its mod operator returns is also a Unicode. So I still don't think it's a bug.

Someday, all will be Unicode, until then, some apps choose to remain Unicode free. Also, there is a build option to not even compile Unicode support -- it would be a bummer to have the $ templates fail as a result.

Maybe. Like the doctor says, well, don't do that! (i.e. use Templates and disable unicode).
