Arpilisp author here. If you were to implement the same Lisp in C then compare, then maybe the assembly variant would be faster for the reasons you mention. Or maybe not. Also, I modeled arpilisp after the original Lisp. That's barely a first step, and possibly the wrong first step, for anything non-trivial, including applications requiring a "super fast lisp that can compete with Go." But I didn't write arpilisp for performance. I wrote it to learn and share. Enjoy!
