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: mapped_helper.rb
    path of file: ./repos/rails_stuff/lib/rails_stuff/statusable
    
    the code of the file until where you have to start completion: module RailsStuff
  module Statusable
    # Helper to hold
    
    
      def initialize(*)
        super
        @mapping = @list
        @indifferent_mapping = mapping.with_indifferent_access
        @list = mapping.keys.freeze
        @inverse_mapping = mapping.invert.freeze
      end
