Rose::Class - A very simple class base class.

error[ERROR]
           Get or set the class-wide error.  By convention, this should be a scalar that stringifies to an error
           message.  A simple scalar containing a string is the most commonly used value.

       Rose::Class is a generic base class for classes.  It provides a single class method ("error"), but may be
       expanded further in the future.

       A class that inherits from Rose::Class is not expected to allow objects of that class to be instantiated,
       since the namespace for class and object methods is shared.  For example, it is common for
       Rose::Object-derived classes to have "error" methods, but this would conflict with the Rose::Class method
       of the same name.
