currently in case of an unhandled throw command, M2 shows error: unhandled throw command proposal: show error: unhandled throw command (use catch) and maybe at user level also in additon show the output as if there was a catch For example, if we had throw "user exception" show

error: unhandled throw command (use catch)
user exception

Both are good ideas.
