Yeah, I managed to reuse my Position and Heading classes from last year after some dusting off. My solution: https://github.com/jorispz/aoc-2019/blob/master/src/commonMain/kotlin/day3/p03.kt

I started using a fancy Sequence-based solution until I realized that I needed the whole history of visited points anyway, so dropped that and just went for creating a ListPosition per wire and find the crossing points as above.

I had made a list of functions I wanted to make for my utils library and scan was actually one of them. Sadly I focused on some other functions first and therefor couldn't use it =/

+1 excited for scan to be added so I can drop custom impls 😄
