Fantastic article but... “ The implementation here is in LISP which is a great language to learn but in my experience a tough language to use on larger projects.”
I was very careful to qualify it with "my experience" :P. I have loads of armchair knowledge about LISP but was never able to commit to a larger project.
What helped you get good at LISP?
Probably just an unhealthy obsession with it at one point in my life. But I do think there have been some pretty major projects built with it when it was in its heyday a few decades ago. It’s definitely not just an academic toy.
