Are you sure you *really* want to inherit from unicode? Don't you want
to store an unicode object as an instance attribute?

Unfortunately, unicode objects don't have a __unicode__ method.

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.

However, unicode(super(Excerpt, self)) is also forbidden because
super() allows attribute access only (why by the way?).

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

How does my object get its own value?

"its own value" is the instance itself
