Hello,

irb(main):001:0> class Myclass
irb(main):002:1>   def play
irb(main):003:2>   end
irb(main):004:1> end

irb(main):027:0> Myclass.class
=> Class
irb(main):028:0> Myclass.superclass
=> Object
irb(main):029:0> Class.superclass
=> Module


Please see the code about, why Myclass.superclass is "Object"? But I
think it should be "Module".

Thanks for your helps.
