Thanks for sharing your code! I am sure many people will use it. And thanks for the kind words about the MPU episode.
In the MPU episode I mention Pop-11. It’s similar in many ways to Lisp, though the syntax is different and has lots of unique features. And it too has its own editor: VED. In fact, the POPLOG system containing Pop-11 (the core language) also supports Lisp, ML and Prolog. I haven’t used it in years however. But I’m on their mailing list and there is still some activity. Poplog was available for a while on the Mac, but that was in the days before the shift to Intel.
