Still pretty new to Elixir, so I welcome any suggestions, but from my understanding (and based on Elixir's guides [1]), I think that the more idiomatic way to approach this is to avoid writing such a loop_through/1 function and instead just use:

  Enum.each(<the list>, &IO.inspect(&1))

or likely

  <series of data transformations resulting in list> |> Enum.each(&IO.inspect(&1))

Both return the :ok at the end of the loop, so Enum.each/2 looks to be functionally equivalent.
