This is unrelated to Nim it's an issue with the csvtools module you can tell cause the code happens inside csvtools.nim before it errors in your code, the exact line that the issue is from: /home/eggplants/.nimble/pkgs/csvtools-0.2.1/csvtools.nim(232, 20) template/generic instantiation ofgenUnpackMfrom here
