Example of debugging fluent style code in Delphi using the identity transformation.
Starting from example code mentioned on StackOverflow : https://stackoverflow.com/a/5104244/8106387 and having retrieved the old code : https://web.archive.org/web/20110227200636/http://paste.ideaslabs.com/show/lzILqOs6PK
I played with an idea that seemed logical from a Functional Programming perspective ... the Identity transformation ... that just returns exactly what you give it.
I didn't know what that would look like in Delphi ... until I tried it.
Code here, plus the original file, and a video of debug stepping through the code.
