Subject: Opinion on ClassInherit Include

So I want to include a module and have methods become part of the class, not 
the instance. What do others think of this approach?

  class Module
    alias :append_instance_features :append_features
    def append_features(klass)
      if constants.include?("ClassInherit")
        klass.extend self::ClassInherit
      end 
      append_instance_features(klass)
    end
  end

Example:

  module MyMod
    module ClassInherit
      attr_accessor :x
      def hix
        puts "Hi, #{@x}."
      end
    end
    # ...
  end

  class A
    include MyMod
  end

  A.x = 'you'
  A.hix  #=> Hi, you.
