Oh well, never mind (I am stupid all right, or my example are stupid ..)

class Array
  def delta other
    p ((self - other) | (other - self))
  end
end

module A
  class Object
    A = 5
   class B; end
   (::Object.constants).delta (::Module.constants)  # => [B]

  (::Object.constants).delta (::Module.constants)  # => []
end
