The 32 bit / 64 bit made a noticeable difference - that was an excellent suggestion. I looked around for a nice way to enforce changes to all my literals and types, and found an example [here](https://forum.nim-lang.org/t/1267#19038) by @Araq that I've modified to be more generic. I love that nim supports this! I may rework it and submit it as a module since it's so useful.
