in reply to Pattern for a shell-style call + error response

One common method in other languages is: 
my $ret = $item->frobinize(...);
die "Error occured." if $ret;

It's clean and simple. I like it better than 'and'.

    The advantage of this method is that you get a handle on $ret, which will usually have some meaning. So you can print it in an error message, or something.
