Going through some old code snippets and came across this clever bit. Back 
then I was planning to use this for Facets, before I finally determined 
that using mixins wasn't actually the best approach for a core extensions 
library.

  module Extension
    def self.included(base)
      name = base.name.split('::').last
      core = eval("::#{name}")
      core.send(:include, base)
    end
  end

Example:

    module Facets
      module String
        include Extension

        def drippy
          puts "Drippy #{self}"
        end
      end
    end

    "Hello".drippy

Just thought I'd share.
