I've been working through the memory requirements of Skate, my Scheme compiler for Z80/CP/M. We have to fit the program, its data and runtime support into 64 KiB, with operating system taking some of that space too. Closures and automatic memory management make for an expressive way to program and making that practical on an eight-bit machine is a challenge I think is worth pursuing. https://semantic-scroll.com/content/2026/09/20/01-room-to-run/ #Scheme #RetroComputing
