There's difference.

  module Dave
    def dave
      # ..
    end
    module_function :dave
  end

works like
  
  module Dave
    def dave
      # ..
    end
    private :dave       # method visibitili change
    def Dave.dave       # copies method body for class method
      # ..
    end
  end

See?
