Yeah, but I think they were added in 5.10, and when possible I try to give examples using 5.8 features. (Something like say is excusable, because it's so easy to write a shim for it. 

sub say { local $\ = "\n"; print(@_ or $_) }
sub IO::Handle::say { my $h = shift; local $\ = "\n"; $h->print(@_ or 
+$_) }

I also quite like this way:

use constant {
    IX_FILENAME => 0,
    IX_RUN      => 2,
    IX_DISTRICT => 8,
    IX_COPY     => 9,
    IX_TOTAL    => 10,
};

print Dumper 
    map {
        Dumper($_), $_->[IX_FILENAME]
    }
    sort {
        $a->[IX_RUN]      <=> $b->[IX_RUN]       or
        $a->[IX_DISTRICT] <=> $b->[IX_DISTRICT]  or
        $a->[IX_COPY]     <=> $b->[IX_COPY]      or
        $a->[IX_TOTAL]    <=> $b->[IX_TOTAL]        
    }
    map {
        [ $_, split /_/ ]
    }
    @files;
