Array class method unavailable on Shoes?

[kita yui]

Hi,
   Array class method seems to be unavailable on the program below. Does anyone 
know about this?
   
  #This code shows only a blank window..
  Shoes.app do
  class Array
    def open
      para self.inspect
    end
  end
  [3,3].open
end

  This is a simple question, so it may be on the mailing list already though, 
I'm not sure how to access the mailing history....Let me know that too.
   
  One more question. My handle name for Yahoo comes up (like  
"my_handle_name"<my mail address>wrote: ) every time I question to this mailing 
list. Does anyone know how to change the name of it?
   
  Thanks..Leui
