Subject: Re: "private" modules

Oh, anonymous module, good idea.
Anyway, since I don't actually want to include stuff into Vector, I 
changed it to this:

module A
  @backend = Module.new do
    def self.bleh
     puts 1
    end
  end

  def A.backend
    @backend
  end
end

module A
  class Vector
    def initialize
      puts A.backend.class
    end
  end
end

Since GSL.backend is a module method, when I do "include A" at the 
top-level, neither @backend nor A.backend are visible.
It would be cool to have something like "private" for modules, so that 
modules defined after that keyword would only be accesible from the 
parent module.

In any case, I'm open to any other idea better than mine.

Matt
