same here, it's a forever top of mind but never to be practically used. The thought of having one language but can dish out frontend in JS, backend in python, jobs in C has been a dream of mine.
https://github.com/c-blake/cron might interest you. This uses "job" from GP in the sense of "cron jobs", although GP meant something much more broad by "jobs in C". ;-)
The key idea is portable to any prog.lang. you might like, although many will not be as run-time efficient as Nim, C, etc. and many may not be as safe as Nim.
