I did that kind of thing when I first started using C (my attitude then was that C was fine, but it should have looked more like BCPL). I stopped after a short time.

> #define LOOP for(;;){

Predicted Rust.

C for people who don't like C. At CompuServe, much of the legacy code base was in BLISS and so there was a header that said

#define BEGIN { #define END }

etc. etc. etc.
