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: names.rb
    path of file: ./repos/anystyle/lib/anystyle/normalizer
    
    the code of the file until where you have to start completion: module AnyStyle
  require 'namae'

  class Normalizer
    class Names < Normalizer
      @keys = [
        :author, :editor, :translator, :director, :producer
      ]

      attr_accessor :namae

      def initialize(**opts)
        super(**opts)

        @namae = Namae::Parser.new({
          prefer_comma_as_separator: tr
    
      def normalize(item, prev: [], **opts)
        map_values(item) do |key, value|
          value.gsub!(/(^[\(\[]|[,;:\)\]]+$)/, '')
          case
          when repeater?(value) && prev.length > 0
            prev[-1].dig(key, 0) || prev[-1].dig(:author, 0) || prev[-1].dig(:editor, 0)
          else
            begin
              parse(strip(value))
            rescue
              [{ literal: value.strip }]
            end
          end
