BTW I've rewrote all #hatis code I had in Guile Scheme in Common Lisp recently.
Now it's based on wayflan library that is just a gem. I'm finally at the point where I can just code my idea in Lisp without any worries about underlying libs.
Take a lot of time to dive into CL from clojure+scheme: asdf + CLOS + some old-school obscurities. But it's all good at the end.
I believe I'll write a second video on the project in a next couple months
