Well, with proficient look-and-feel and proper bindings (both on
keyboard and mouse) it is not so small work IMHO...

Megawidgets in ruby...? I didn't try it yet, but sounds good... I have
some questions:

This is from tk.rb:

module TkComposite
  include Tk
  extend Tk

  def initialize(parent=nil, *args)
[...]

What does it mean if a module has an initialize method? E.g.

class A
	def initialize
		...
	end
end

class B < A
include TkComposite
	def initialize
		...
		super # it calls TkComposite#initialize or A#initialize?
	end
end

For automatically initializing a module, I wrote my own 'before' hack;
it was unnecessary? (Although, it calls the ascendant's method even if
super is not called...)

I will look about this TkComposite...
