Ha, ha! It never occurred to me!

#!/usr/bin/perl
use strict;
use warnings;
my $prefix="Prefix: ";
sub print_prefix {
    print $prefix, @_;
}
print_prefix "alpha ", "beta ", "gamma\n";

Sigh. When I read your reply, I thought, "Hmm, does unshift return a reference to the array?", so a first I thought you were prompting me to do something like:

print unshift @_, $prefix;

But when I checked the docs, I could see that it wouldn't fly. Then I understood what you meant. Ah, well! I'm always amused at how my mind works: it seems I frequently complicate simple things. ;^)
