Anyone planning on solving Advent of Code 2020?

I always start with excitement and then get busy on 9/10th day. This year, like the year before this, and the year before that, I intend to be regular. My language of choice this year would be Elixir (and/or Dart depending on my mood on the day). Anyone else going to solve Advent of Code puzzles starting tomorrow?

Waiting for the first one to unlock https://adventofcode.com/

What are your tips for language and framework creators?

If you had the ear of a language creator, what would you say - what could they do to make a language that you would use? :upside_down_face:
