# This an example of how a runtime exception inside of a flow
# sends a :normal exit message.
#
# To run this code add the Flow dependency to the mix.exs file:
# {:flow, "~> 0.11"}
#
# The behaviour that I get is the stacktrace is printed to STDOUT,
# and the flush() function outputs a message like this:
# {:EXIT, #PID<0.144.0>, :normal}
# But I am expecting a non-normal exit message.

Process.flag(:trap_exit, true)
