Here’s my solution: day7.ex · GitHub

Here is my solution.
In part 1, I spent a significant amount of the time to implement my permutations function to lazily generate all phases.
In part 2, I spent some time before I realized that it would have been much easier to run each of the amplifiers in their own Erlang process and rewrite input/output to use message passing. Oh, well! I didn’t do that refactoring, but made the machine suspend on an output operation and saving the IP to make it possible to resume it later when I had new input for it.

Very nice, super clean. I did want to try processes + messages, which would have been the Elixir/Erlang way, but I am just not that comfortable with all that stuff yet.
