Thanks for a detailed response!

I also use Nim quite a bit on linux/windows for machine-learning purposes. But even on these systems, It is generally a pain to try to trick Nim into using a compiler not directly supported, as some original hard-coded flags would be incompatible with the one i am trying to use,for example NVCC .

Follow up question, Do you generally use Nim on ESP like chips which run some form of a RTOS, or also on bare-metal micro-controllers ?
