this is the emacs language workbench by the way, one of those things where every part of it is fun to implement (so far)

a language workbench lets you freely define, use, and splice together programming languages. mine lowers languages into s-expressions and then either code inside your running emacs session or a native binary via QBE IR

currently it just does brainfuck and other toy languages, right now I’m tackling the multi-language REPL and then I’m gonna do a useful language

I hope this’ll be useful for other people, but for me it has so much potential already
