Class instances may override class attributes by creating local attributes
of the same name, in which case Class.class_attr and self.class_attr may
not be equal, so you'd have to use the correct one for your needs.

If you're sure that an instance does not override the class attribute,
then you can use whichever one you prefer.  self.class_attr may be more
convenient because you don't have to provide a specific class name.
