Rereading the about.md docs for these languages, I found several broken or missing links, plus the usual scattering of minor typos.
I have a couple of PRs ready to submit, to fix these small issues.
Quite a few of these about.md docs look a bit unfinished, probably because the author (Erik) had at least a million other things to do and didn’t give them the same priority as the introduction.md. The 25 or so F# issues for new concepts, open since 2020, hint at the same problem. I’d love to be able to help, but I need to go away and learn more about both languages first…
