Metable - The Bonus Mixin

Metable is a mixin that provides a bundle of handy methods for the aspiring ruby metaprogrammer.

Have you ever wanted an easy way to alias a class method? Check out alias_class_method. Have you ever desired a clean way to dynamically define a class method in the same manner you would an instance method using define_method ? Well feast your eyes on define_class_method. In fact, you can dynamically define a singleton method on any object the same way with define_singleton_method.
