interesting. Not specifically relevant to this regex implementations but I would say that regexes are one of those things that I never could really get into my head. I tried for many years but can't memorize the pattern needed, and can't write anything on my own but the most simplex regexes. I used to envy people that could do that. It's mostly about how your own memory work, I guess. Luckily recently I don't have to remember any of this anymore thanks to llms.
