Hmm... I may again have overshot the solution. It's easy enough to
privatize methods as needed, one doesn't need a intervening module to
do that. So I'll push this back to a BlankSlate like class.

Also, I see now where the limitation on the dynamic behavior actually
lies:

  class X
    private :q
  end

  NameError: undefined method `q' for class `X'
        from (irb):2:in `private'
        from (irb):2
        from :0

As with my method annotation system, one might wish to _predefine_ a
characeristic, in this case the visibility of a *potential* method. In
this way it could even be reused. Eg.

  module Shh
    private :s
  end

  class S
    include Shh
    def s
       "s"
    end
  end

  S.new.s  #=> Error private method

Possible?
