** (EXIT from #PID<0.132.0>) shell process exited with reason: :jopa

Interactive Elixir (1.9.4) - press Ctrl+C to exit (type h() ENTER for help)

...
The following behaviour applies if reason is any term except :normal or :kill:
1. If pid is not trapping exits, pid will exit with the given reason.
2. If pid is trapping exits, the exit signal is transformed into a message {:EXIT, from, reason} and delivered to the message queue of pid.
