Yes, and the attempt at the idiom is a reasonable idea, I have in fact used it for service/daemon style scripts in the past, but exit 0; # undef works too is the only "correct" exit code. Everything else is an error state. Since returning false is suggestive of an error in Perl I am reticent to put that lipstick on this pig... or this pig stick on those lips... And that's the way the news goes!
