I’m working on a project that awaits an :ok signal while also trapping and awaiting any exits that happen midway. Looks something like this:

  Process.flag(:trap_exit, true)
  # Call a process that will send() back :ok after some time
  receive do
    :ok -> :nice
    {:EXIT, pid, reason} -> :bad
    {:EXIT, reason} -> :bad
  after
    10_000 ->
      :timeout
  end

The issue is that if there is an :EXIT that happened prior to running this function, it will instantly return :bad. So I was thinking about adding something like :c.flush() to clear out the mailbox before we start the receive, however I’m not really sure if this is really a good idea. Or perhaps I’m going down some dark path that I shouldn’t go into…

Would love to hear your opinion
