I remember reading about Elixir (or was it Erlang) and tried to follow a tutorial and trying to solve some simple exercises. I don't remember the details but I do remember writing the simple functions and they just stacked and fit like Lego bricks. I kept thinking that I will get stuck but I didn't and just kept going. Didn't have to engage in any flow-control or if/else etc. It was nothing like I had seen before. Unfortunately my curiosity pivoted to something else and I didn't complete it but I hope to swing back to Elixir someday soon.
