Yeah, I clearly missed on that one. I then tried:

sub print_prefix {
    local $/="\nPrefix: ";
    print @_;
}

But that didn't work. On first guess, I thought it would do OK. After reading the documentation, I thought it would print it at least once. But what I got was...nothing. It never printed prefix at all. The only other methods I could think of had already been covered.
