Perhaps a funny question, but - is there an analogue of "C# extension methods" in Delphi?

Question

Delphi

I don't even know what's better? quote? or provide a link? there was a question about debugging in C #, there I just illustrated my favorite tricks .. I'll try to make a big quote:

you can implement your simplest logger as an extension (in a utility static class), example

internal static void log(this string txt) => tbLog.AppendText(txt + Environment.NewLine);

then very convenient to use anywhere

$"что то прошло не так, параметры первый {} и второй {}".log();

... and more convenient compiler options, for constructs that are clearly not needed in production

#if DEBUG
            var sw = new Stopwatch();
            sw.Start();
#endif
            /// что то делаем
#if DEBUG
            sw.Stop();
            var ts = sw.Elapsed;
            $"total time:".log();
            $"\t{ts.Hours:00}:{ts.Minutes:00}:{ts.Seconds:00}.{ts.Milliseconds:000}".log();
#endif

.. I repeat - Delphi is released by the community ... but after the sweet habits ... is it worth it?
another question - if there are still saccharins there
ps if there are saccharins in Lazarus - I will still be grateful for the info

Extension method : XE3+, helper class.

Conditional compilation : ever since Pipe Pascal, compiler directives

{$IFDEF DEBUG}
{$ENDIF}
