FWIW, it has helped me to add “write the most concise and idiomatic elixir code possible” to any prompt (or to the project’s general instructions). Especially when learning Elixir, I often was writing code based on old habits (too many if statements etc), and the AI code really accelerated my learning. Also, asking it to write my own “bad” code using more idiomatic Elixir was often enlightening.
