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: locales.rb
    path of file: ./repos/ekylibre/lib/clean
    
    the code of the file until where you have to start completion: module Clean
  module Locales
    class Scrutator
      attr_reader :to_translate, :untranslated

      def initialize
        @to_translate = 0
        @untranslated = 0
      end

      def exp(hash, *keys)
        options = keys.extract_options!
        name = keys.last
        @to_translate += 1
        value = rec(hash, *keys)
        yaml = Clean::Support.pair_to_yaml(name, value || options[:default] || name.to_s.humanize)
        unless value
          @untranslated += 1
          yaml.gsub!(/^/, Clean::Support.missing_prompt)
        end
        yaml
      end

      def rec(hash, *keys)
        key = keys.first
        if hash.is_a
    
      def clean_enumerize!
        translate('enumerize.yml') do |ref, translation, s|
          translation << "  enumerize:\n"
          ref[:enumerize] ||= {}
          Clean::Support.models_in_file.each do |model|
            next unless model.respond_to? :enumerized_attributes

            attrs = []
            model.enumerized_attributes.each do |attr|
              next if attr.i18n_scope
              next unless attr.values.any?
              next if model < ApplicationRecord &&
                      model.nomenclature_reflections.detect { |_k, n| n.foreign_key.to_s == attr.name.to_s }

              attrs << attr
            end
            next unless attrs.any?

            translation << "    #{model.name.underscore}:\n"
            attrs.sort_by(&:name).each do |attr|
              translation << "      #{attr.name}:\n"
              attr.values.sort { |a, b| a <=> b }.each do |value|
                translation << s.exp(ref, :enumerize, model.name.underscore.to_sym, attr.name, value.to_sym).dig(4)
              end
            end
          end
        end
      end
