I've been using Elixir, which has been wonderful, mostly because of how amazing the built in `Enum` library is for working on lists and maps (since the majority of AoC problems are list / map processing problems, at least for the first while)

Enum really does feel like a superpower sometimes. I’ll knock out some loop and then spend a few mins with h Enum.<tab> and realise it could’ve been one or two Enum functions.
