What if YOU Could Add Your Own Features to a Language?

I made a video explaining a concept I love called macros, which allow you to add your own syntax to a language. Languages like Rust, Lean, and lisp have them. The goal with the video is to make you feel like you could've discovered macros yourself. I'm new at making educational content like this, but I'm planning on making many more programming language videos like this one on my channel. Any thoughts, constructive criticism, or advice is more than welcome! Hope you all enjoy
