Just seeing this thread now, but I've been posting my solutions [in this repo](https://github.com/DestyNova/advent_of_code_2022). Most days I've used Nim but there are a few Crystal solutions too, especially in the earlier days before I got too lazy. A few times I used ChatGPT to translate my solutions from one language to another. It produces sort-of-mostly correct Nim which is amazing really.
Just for fun I added a little benchmark script using hyperfine, but so far the problems have been very computationally easy so they don't really tell us anything. But I know my Nim solution for today (day 11) is more than 100x faster than someone's Python solution I watched in a stream recording later. Also, I'm really impressed with Nim's memory usage. I'm using `--gc:orc` but it's frugal either way. Really enjoying this so far.
