** Class: RCBase (mixin)

** Generally mixed into every base class. The functions in this class are all
** static. Therefore this entire class is just syntatic sugar. It gives the
** illusion that errors (in particular) are retrieved via the same object
** that just reported a failure. It also (unfortunately) might lead one to
** believe that the errors are persistent in that object. They're not.
