BTW in case anybody is looking for help learning Nim, the Nim Discord was pretty helpful. I wrote a simple text file parser and ran into an annoying issue with the compiler reporting indentation errors which were really issues unrelated to indentation, so I asked there.
Turns out they have a community pastebin-type compiler for sharing code, and within a few minutes a couple others shared back fixes to my source. Really convenient compared to pulling one's hair out for a couple hours...
