Brendan Hansknecht (Oct 03 2022 at 18:35): Brendan Hansknecht (Oct 03 2022 at 18:35):I just implemented day 4 in what feels like a slightly silly way. That being said, it was quite fun to implement this way even if it is doing work it really shouldn't be. The solution felt nice to write.

I've tried my best to error instead of default values, which kinda feel icky. Also, loving that I don't have to write any type annotations at all. Hopefully the editor does this automatically in the future.

I've been a bit frustrated to unwrap values from inside a Tag. I don't know how to do it without a when.
