البته آقای Jake Archibald کد جالبی را برای این قابلیت پیشنهاد داده‌است که ترکیبی از import استاتیک ES6 می‌باشد:

  {
     Console.WriteLine( "this is main block of code" );

            {
                File.Create( path );
            }
            lock ( lockObject )
            {
                using ( TextWriter writer = new StreamWriter( path , true ) )
                {
                    writer.WriteLine( string.Format( "{0} at {1}" , methodName , DateTime.Now ) );

            }
        }
    }

    {

            return methodReturn;
        }

        public int Order { get; set; }
    }

 var methodReturn = getNext()( input , getNext );

 public class LogAttribute : HandlerAttribute
    {
        public override ICallHandler CreateHandler( Microsoft.Practices.Unity.IUnityContainer container )
