Nim
I have zero idea how this functions correctly. I fear to touch it more than necessary or it would fall apart in a moment.
I got second star after 8 hours (3 hours for part 1 + 4 hour break + 1 hour part 2), at that moment I've figured out how to mark edges of enclosed tiles. Then I just printed the maze and counted all in-between tiles manually. A bit later I've returned and fixed the code with an ugly regex hack, but atleast it works.
Code: day_10/solution.nim
I printed the loop using box drawing characters, zoomed out, took a screenshot, and used GIMP to separate the inside and outside, and count the number of inside tiles.
haha, thats genius
