Thank you for introducing Easy-ISLisp. I'm the author, Sasagawa. Racket is incredibly excellent. I used it back in the days of MZ-Scheme. I believe it's an extremely capable implementation. There are many other outstanding Lisp implementations as well. Easy-ISLisp is remarkably simple. If you look at the source code, you'll quickly understand its mechanics. During the early days of personal computers, I had a lot of fun analyzing, modifying, and extending Basic interpreter. I express that kind of playful spirit as friendliness. Modern implementations are highly polished, making it difficult to perform internal analysis for simple tasks. So, please enjoy Easy-ISLisp with a mindset similar to modifying vacuum tube amplifiers.
