I have a situation where I need to try multiple things and if any of them succeed I want to stop. However, I also need to do something if none of them succeed. I am currently using a very ugly construct kind of like this: 
my $success = 0;

foreach my $try (@options) {
    if (exists $hash{$try}) {
        do_something($try);
        $success = 1;
        last;
    }
}

if (!$success) {
    log_failure();
}

Can anyone suggest a nicer way to do this? I particularly dislike the use of the $success flag. In my real code, I have many conditions to check and have to put the flag setting code and the "last" statement after each one, which feels redundant.
