For a short while, I ran the Eumel operating system and wrote an application in Elan. Among other interesting properties, files weren't saved, but were checkpointed by the OS. I enjoyed this exercise, although Eumel remained a very small niche.

Cool, thanks for the link.

I have not heard of Pancake, seems interesting. It led me to https://cakeml.org. Looking at https://github.com/CakeML/cakeml/blob/3194e00b69ce817cf47751..., I feel quite dumb. :P
