    # may be preferable.
    def self.load(row)
      new(*load_fields(row))
    end

    def initialize(*args)
      if args.size == 1 and DBI::Row === (row = args[0])
        args = self.class.load_fields(row)
      end
      super(*args)
    end
  end

I'm uncertain if DBI may have more convenient method.
