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: truffleruby_object.rb
    path of file: ./repos/brew/Library/Homebrew/vendor/bundle-standalone/ruby/2.3.0/gems/concurrent-ruby-1.1.4/lib/concurrent/synchronization
    
    the code of the file until where you have to start completion: module Concurrent
  module Synchronization

    module TruffleRub
    
        def attr_volatile(*names)
          names.each do |name|
            ivar = :"@volatile_#{name}"

            class_eval <<-RUBY, __FILE__, __LINE__ + 1
              def #{name}
                full_memory_barrier
                #{ivar}                  
              end

              def #{name}=(value)
                #{ivar} = value
                full_memory_barrier
              end
            RUBY
          end

          names.map { |n| [n, :"#{n}="] }.flatten
        end
