First - awesome job. Congrats. Self hosting is an accomplishment!
But I'm curious to get your thoughts on the process in hindsight.
I understand why it's valuable: to cast a wide net in catching bugs and give a good signal that your language is generally "ready".
I'm working on a similar language, but worried about going down the self-hosting path, as I think it'd slow me down rather than speed me up.
How did it work for you?
