Pleased to announce shplait/liquid, a liquid-typed version of shplait, the language of my book PLAI. This version adds liquid-typing, a form of refinement types. It's primarily meant to be a small language for pedagogic purposes to induce people to try grown-up ones later. ↵

I don't agree with every technical idea here, but I absolutely agree with the spirit. Now you can make your crazy dreams happen! Go forth and explore!
Should YOU do Programming Languages research in era of LLMs? Many would say NO. But I say YES! PL Research is dead? Nay! the era of PL Exploration is just beginning. Fuck the users. Fuck the applications. Let's do some fucking PL research! kirancodes.me/posts/log-end-…
