Or if you like pipelines as much as I do, you can write it as: [:a, :b, :c] |> Enum.with_index |> Enum.each(fn({item, counter}) -> IO.puts("#{counter}

This is interesting. I'm a huge fan of pipelines like that and I think they're unmatched for being able to compose operations well, but I prefer the non-pipelines version of what is basically just an imperative loop.
