Hot take, but the main problem with this is that you have to type variables or use them in larger expressions. Otherwise I like it.
These would make a great mouseover text. I don't know if there's any standard way to support that. Actually, how come coding in non-plaintext formats never took off?
I need like a tutorial on IDEs, because clearly I'm using them wrong. Or I tend to work on things that are poorly documented and just haven't been able to take advantage, I guess that's possible.
