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: settings.rb
    path of file: ./repos/bundler/lib/bundler
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module Bundler
  class Settings
    autoload :Mirror,  File.expand_path("mirror", __dir__)
    autoload :Mirrors, File.expand_path("mirror", __dir__)
    a
    
    def converted_value(value, key)
      if is_array(key)
        to_array(value)
      elsif value.nil?
        nil
      elsif is_bool(key) || value == "false"
        to_bool(value)
      elsif is_num(key)
        value.to_i
      else
        value.to_s
      end
