```ruby

    included do

      def set(**attributes)
        attributes.each { |key, value| instance_variable_set(:"@#{key}", value) }
      end

      ##
      # Returns true if two objects have the same type and id
      #

        other.is_a?(self.class) &&
          id == other.id
      end
    end
  end
end
```

Use setter instead of instance_variable_set
