It's not an identical response, but a Class value that is printed the same
way :) It happens all the time in irb. Perhaps we should fix Class#inspect
and/or Class.to_s .

batsman@tux-chan:/tmp$ cat e.rb
module X1
end

module X2
end

class XX
  def XX.record(*mods)
    x = XX.clone
    x.class_eval { include *mods }
    return x
  end
  def initialize
    puts self.class.included_modules
    puts self.class
    puts self.class.id
    puts
  end

  def XX.inspect
          "<Class XX: #{self.id.to_s}>"
  end

  def XX.to_s
          "<Class XX: #{self.id.to_s}>"
  end
end

xx = XX.record(X1, X2).new
yy = XX.record(X1).new

puts "XX: #{XX.id}"
batsman@tux-chan:/tmp$ ruby e.rb
X2
X1
Kernel
<Class XX: 538072072>
538072072

X1
Kernel
<Class XX: 538070822>
538070822

XX: 538072512
