Something that always bugged me about Lean is how unreadable and unwritable.

Math uses extremely heavy notation to make statements concise. It's hard to learn the notation without a visual reference guide, sync the symbols don't have guessable names, but once you know what the symbols mean, it's readable.

Java is incredibly verbose but you can make out what it's saying word by word

Lean is line noise. It's like assembly language for math, which is great, but not what humans should be using day to day.

This Litex does a nice job of being concerned about humans reading and writing the code.

Do you have an example Lean statement you struggle with? I would have posed that they're "just" using standard math notation that should be explained in the relevant textbook for the math you're trying to formalize, but perhaps they are indeed cooking...
