#sub SIG {...} # takes a list of signals you expect it to die with
#sub ANYSIGBUT {...} # must die with a signal, just not ones you specify
#
#But PASS AND FAIL are probably what you want immediately and if not
#supplied, then defaults to PASS. The returned structure should have whether
#or not the expected result happened.
#
#Of course, you'd call the expect_result function inside of the new_system()
#call.
#
#As for what happens of the expected event doesn't happen, you can supply
#{die_on_failed_expectation => 1} and that is set to true by default.
#
#With expect_result and die_on_failed_expectation, you can model something
#like running a command which might or might not fail, but you don't care
#and it won't kill the script.
#
#$ret = new_system("foobar 1 2 3 4", {expect_result => ANY});

#Since ANY always returns true, then you can't ever fail in the expectation
#of the result so the default die_on_failed_expectation => 1 will never fire.
