You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: taxonomy.rb
    path of file: ./repos/artichoke/artichoke-backend/src/extn/stdlib/vendor/gen/rss/maker
    
    the code of the file until where you have to start completion: # frozen_string_literal: false
require_relative '../taxonomy'
require_relative '1.0'
require_relativ
    
      def self.install_taxo_topics(klass)
        klass.module_eval(<<-EOC, __FILE__, __LINE__ + 1)
          class TaxonomyTopics < TaxonomyTopicsBase
            def to_feed(feed, current)
              if current.respond_to?(:taxo_topics)
                topics = current.class::TaxonomyTopics.new
                bag = topics.Bag
                @resources.each do |resource|
                  bag.lis << RDF::Bag::Li.new(resource)
                end
                current.taxo_topics = topics
              end
            end
