Here's one way:

module DefineClass
  def self.included(other)
    other.class_eval {
      define_method :class do
        other
      end
    }
  end
end

class SO < BasicObject
  include ::DefineClass

  @@counter = 0
  def initialize(*a, &b)
    super
    @@counter += 1
  end

  def clone
    clone = self.class.new
  end

  def inspect
    "<#{self.class}: #{@@counter}>"
  end
end

s = SO.new
p s.clone

# => <SO: 2>

(I'm not a huge fan of @@class_variables in general - it's just here
to make the point that there are two different instances.)
