Trying decorators to check if implicit tracing would be a good idea.

reports.ex

defmodule Reports do
  use Decorator.Define, [trace: 0]

  def trace(body, context) do
    quote do
      try do
        unquote(body)
      rescue
        e ->
          IO.puts("Erro: " <> e.message)
          IO.puts("Stack: " <> inspect(__STACKTRACE__))
      end
    end
  end
end

defmodule A do
  use Reports

  @decorate trace()
  def division_by_zero(a), do: a / 0
end
