Validation::Class::Backwards is responsible for providing deprecated
functionality to the Validation::Class::Prototype layer whilst clearly
remaining separate via namespacing.

Note: The methods described here will eventually become obsolete and cease to
exist. Please review the namespace occasionally and adjust your code

The error method is used to set and/or retrieve errors encountered during
validation. The error method with no parameters returns the error message object
which is an arrayref of error messages stored at class-level.
