Hey Greg!  That works great from Terminal - thanks.

I changed your example to work with Sketchup, and by writing it like 
this, I got it work under Sketchup as I want:

(The UI.messagebox put up a dialog box, similar to  a javascript alert() 
box )

require 'sketchup.rb' ;
include UI   # <== this is the key to getting this to work

messagebox "Regular Messagebox..." ;

module UI
  extend self
  alias_method :messagebox_old, :messagebox

  def messagebox (string)
    puts "aliased method: #{string}"
  end
end

messagebox "this should show up in the console" ;

module UI
  alias_method :messagebox, :messagebox_old
end

messagebox "Back to normal" ;

In the above case, I get a popup, then a message to the Ruby console, 
then a popup.  Perfect.
However, from all my code, I typically never "include UI" and write 
scripts like thi, qualifying the messagebox method with UI.messagebox...

require 'sketchup.rb' ;

UI.messagebox "Regular Messagebox..." ;

module UI
  extend self
  alias_method :messagebox_old, :messagebox

  def messagebox (string)
    puts "aliased method: #{string}"
  end
end

UI.messagebox "this should show up in the console" ;

module UI
  alias_method :messagebox, :messagebox_old
end

UI.messagebox "Back to normal" ;


Adding the UI. qualifier, the aliased method is never called and I get 3 
popups.
Any ideas?
