Here's some real code from our work system (variable names have been changed):

    invoice_id
    |> Audit.get_entries()
    |> Enum.map(fn entry ->
      entry.action 
    end)
    |> Enum.map(fn action ->
      to_string(action) 
    end)
    |> Enum.join("\n")

Tell me you can write that as an "easier to understand" set of loops. Tell me that this code is "write-only" and that you don't immediately understand what is happening, without even knowing the language it's in.
