base class for virtual base classes

Class::Virtual is a base class for implementing virtual base classes (what some people call an abstract class). Kinda kooky. It allows you to explicitly declare what methods are virtual and that must be implemented by subclasses. This might seem silly, since your program will halt and catch fire when an unimplemented virtual method is hit anyway, but there's some benefits.

The error message is more informative. Instead of the usual "Can't locate object method" error, you'll get one explaining that a virtual method was left unimplemented.

Subclass authors can explicitly check to make sure they've implemented all the necessary virtual methods. When used as part of a regression test, it will shield against the virtual method requirements changing out from under the subclass.
