Subject: Re: Why class returning its own name when "include" statement?

@Stefano Yes you are right. The below code is proved that.

*********************************************************
 module Show
 def show_string
 p "hi"
 end
 end
# => nil
  class Foo
  @x=12
  (include Show).object_id
  end
# => 10681980
  class Too
  @x=12
  (include Show).object_id.inspect
  end
# => "10648020"
*********************************************************

Does that mean @x has been already initialized? or curious to know what 
"10648020" contains into it?
