Not really a question, but if you ever get to the point of wondering what a good next challenging project would be, consider generalizing some of these techniques into a next generation Yacc / Bison replacement.

Something that can take generic grammer rules and turn it into a high performance parsing engine.

It wouldn't have to support every possible grammar or option. Json isn't that complex of a language, but even a limited set of grammar options in exchange for a performant parser could be of benefit for a very large set of problems.

I've written my fare share of performant code over the years, but this is some next level shit. I've been reading it the last few hours. The only question I have is what is the term for that place considered two degrees past black magic? Since you live there, I have to assume you know the name.
