I was going to say "wouldn't BQN have dicts since it's trying to be a more accessible, modern, from-the-ground-up designed APL and dictionaries are pretty damn useful?" but then I noticed your username so I guess that answers that.

So now I'm curious: why didn't you include some version these features in BQN? They seem pretty nice to have!

EDIT: will you ever write a "let's learn BQN by figuring out how the self-hosted compiler is implemented!" article? I doubt I'll use BQN soon but I find it a fascinating, extremely interesting language, and I'm just super-curious how you implemented the self-hosting compiler.
