I thought this was a great article! I've used Elixir professionally for several years and it all rings true to me. The bit about Keyword lists I think doesn't mention the biggest aspect of it as I think about it: erlang compatibility. I don't think they make a ton of sense in a vacuum, but a list of 2-tuples where the first element is an atom has been the convention for function arguments in Erlang for a long time, as I understand it. And so Elixir kind of adopted it as well, since it inter-operates with Erlang so much and so well. I think a good "map" implementation wasn't even available in the early days of Erlang? So, basically I just kind of "go with the flow" and use keyword lists for the final `opts \\ []` parameter of a function, but basically nowhere else. I also agree with `for` comprehensions. I use it when meta-programming function definitions, but hardly anywhere else. Also, I forgot that `unless` even exists! I don't think I've seen it in any code since my ruby days 7 years ago.
