I'm glad you liked it! I have one more post planned for this series, on par and using continuations for classical logic proof terms. I have two other posts in the works but they aren't part of this series, which will only have that one more post.
Much of what I learned was from blog posts like this one, or at least they got me to the point where I could understand the papers on my own. Blog posts, YouTube, reddit, discord, all helped me a ton. Originally I just wanted to make a cool programming language, but the more research I learned the more my interest shifted to the research, because it's just so unbelievably gorgeous and elegant!
