POPLOG was more than a LISP! It was an IDE for POP-11, Common Lisp, Prolog, and Standard ML. All other languages were incrementally compiled to POP-11. Lisp was the least used of these in my experience at Sussex. \sidebar: POP-11 has Lisp-y list support with a Pascal-like syntax. It was pretty nice. It had assignment the right way around (if you have the stack as a mental model): 5 -> x Grad students and undergrad keeners were advised to learn enough LISP to read papers from the MIT AI Lab :) https://en.wikipedia.org/wiki/Poplog https://en.wikipedia.org/wiki/Poplog It was pretty well done, but not exactly fast on a 1990 Sun minicomputer shared by a hundred students. Almost all of our undergrad assignments were set and submitted via the POPLOG system, including lecture notes and tutorials: 'teach texts' with hypertext links. You could highlight code snippets with the cursor and run them in the REPL. All pre-web on a VT-100. Great stuff.
