Including a module in ruby inherits nested classes. This is an example.

gistfile1.rb

module JohnsThings
  class AwesomeTool
    def is_awesome?
      true
    end
  end
end

class HurricaneTool
  include JohnsThings

  def is_awesome?
    AwesomeTool.new.is_awesome? # This works! Even though I'm not in JohnsThings namespace
  end
end

ht = HurricaneTool.new.is_awesome? #=> true

HurricaneTool::AwesomeTool #=> JohnsThings::AwesomeTool

Yay Ruby!!
