Subject: Re: best way to 'hide' a method when method_missing is in town

What about this solution ?
class HidenMethod < Exception; end
module Hide
  def self.included(klass)
    klass.class_eval <<-END_TXT
      @@hidden_methods = []
      def self.hide(method)
        private method
        @@hidden_methods << method.to_sym
      end

      def method_missing(method, *args)
        raise Hide::HidenMethod.new("Hidden \#{method} called.") if
@@hidden_methods.include?(method)
        super
      end
END_TXT
  end
end

class Base
 def method_missing(method, *args)
   puts "#{method} caught in base"
 end

end

class Sub < Base
 include Hide
 def see_me
   puts 'hi'
 end

 def no_see
   puts 'hidden'
 end
 hide :no_see
end

s = Sub.new
s.see_me
s.no_see
