Thanks I understand what you are saying... however consider the 
following example from whys guide (and maybe im missing something here 
again...)
http://www.poignantguide.net/ruby/chapter-4.html#section3

wordlist.rb
===========================================================
  code_words = {
    'starmonkeys' => 'Phil and Pete, those prickly chancellors of the 
New Reich',
    'catapult' => 'chucky go-go', 'firebomb' => 'Heat-Assisted Living',
    'Nigeria' => "Ny and Jerry's Dry Cleaning (with Donuts)",
    'Put the kabosh on' => 'Put the cable box on'
  }
===========================================================

i assume this should be saved to a file too...?
===========================================================
  require 'wordlist'

  # Get evil idea and swap in code words
  print "Enter your new idea: "
  idea = gets
  code_words.each do |real, code|
    idea.gsub!( real, code )
  end

  # Save the jibberish to a new file
  print "File encoded.  Please enter a name for this idea: "
  idea_name = gets.strip
  File::open( "idea-" + idea_name + ".txt", "w" ) do |f|
    f << idea
  end

This doesnt work either. For me at least. Any ideas?
