The "actual value of the instance", given that it inherits from
unicode, is... self.
Are you sure you *really* want to inherit from unicode? Don't you want
to store an unicode object as an instance attribute?

Because it's not needed; unicode objects are already unicode objects,
and since they're immutable, there is no need to duplicate them. If it
existed, would always return self.

(because its purpose is to allow cooperative methods in a multiple
inheritance hierarchy)

"its own value" is the instance itself
