advent-of-code-dev VS Advent-of-code

I never actually want it to return Nothing, but the framework I'm using wants a Maybe.

In my continued attempt to get mstksg's AOC template working, I temporarily gave up on my MacOS attempt (thanks again /u/simonmic for the help so far!) and switched to my Linux box. After a long failure trying to use apt-get install haskell-platform and getting unfixable (by me) dependency errors, I switched to using ghcup (why do we even have haskell-platform if it's not going to work?), and things seem to be compiling and running.

I'm trying to run mstksg's AOC template, but I'm guessing this is a generic issue. When I `cabal run` the executable, I get errors like:

My Haskell solution (using Justin Le's scaffolding):

Justin Le has an awesome development framework for AOC in Haskell: https://github.com/mstksg/advent-of-code-dev.

Wow, almost identical to mine: https://github.com/MichalMarsalek/Advent-of-code/blob/master/2022/Nim/day6.nim

This year I was writing two sets of solutions in Nim. The first one focuses on idiomatic, nice and short and readable Nim. The other focuses purely on speed. The combined running times of the fast solutions is 130 ms. Please let me know if you have any tips on how to make my solutions more simple and/or idiomatic.

Beautiful Nim! My solution is actually very similar.
