Well, does it work in Ruby? NO! So it doesn't work in RubyJS as well :)
It's a bit more advanced than converting "document" from Ruby plainly 
into "document" in Javascript. 

If you want to insert Javascript code directly into your Ruby code, use 
backticks:

  def puts(str)
    `document.getElemementById('STDOUT')['innerHTML'] += str + "\n"`
  end

In the next step, I've planned to port Google's Webtoolkit (or Python Pyjamas) 
to RubyJS.

See above :)
