These koans use Enum.member? and MapSet.member?. I only know a little Elixir, but as far as I can tell these offer no benefit over in/2 (they're the same speed and give the same results).
Similarly, MapSet.equal?/2 is used instead of ==/2, but it doesn't need to be.
According to the docs the in/2 "operator" is simply a macro that translates to Enum.member?/2. I would say that the koans should teach this if possible, so rather than simply replacing them, we should introduce both 🙂

Thanks for writing/maintaining these koans!
