So the "program Fortran in any language" (using only arrays as illustrated in the linked paper[1]) is interesting. I didn't know it was called that since I didn't learn Fortran. (I just flashed back to a memory of someone I worked with around 2000 who said he wrote Fortran in Perl.) Once, I was in a hurry to write a Tetris clone using pygame library, and was just starting to learn Python, so I read just enough of the Python tutorial to get started (but didn't get to classes) and then wrote it without any classes (structures), and just used all parallel arrays instead. It reminded me of the way I originally learned to write text adventures in Basic (from a short book in the 80s about how to do that, by Christopher Lampton).[2] I've been interested in Forth lately, so it was interesting to see him bring that up as well.
