I think the best way (and mostly how existing libs are written) to do this is by creating a class within the module that deals with all the logic, and the module just provides a convenient method, e.g.

module GTranslate
  class Translator
    def perform( text ); translate( text ); end

    private

    def translate( text )
      # do some private stuff here
    end
  end

  def self.translate( text )
    t = Translator.new
    t.perform( text )
  end
end
