On a more serious note, have you thought about trying to aim lightning at the same spot again and write another book about implementing something most programmers take for granted?
I've definitely thought about writing a third book. I don't know if it would be about "something most programmers take for granted". I'm more interested in writing about whatever happens to excite me the most at that time.
I may be projecting, but I feel like the kind of person to get excited about crafting interpreters wod also get excited about crafting databases or OSes.
Maybe! It's definitely getting there. I suspect "semi-arbitrary subset of C" still has me beat but who knows for how much longer.
