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: class_methods.rb
    path of file: ./repos/rom/lib/rom/support/configurable
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

require "set"

require "rom/support/configurable/dsl"
require "rom/support/configurable/methods"
require "rom/support/configurable/settings"

module ROM
 
    
      def __config_reader__
        @__config_reader__ ||=
          begin
            reader = Module.new do
              def self.define(name)
                define_method(name) do
                  config[name]
                end
              end
            end

            if included_modules.include?(InstanceMethods)
              include(reader)
            end
