note Aristotle <blockquote><p>It's a lot longer and wouldn't fit on a slide</p></blockquote> <p>I don't see why it has to be. You can level the playing field without any significant difference.</p> <code> use Benchmark qw( timethese ); my @files = glob "/bin/*"; timethese( -2, { Ordinary => sub { () = sort { -M $a <=> -M $b } @files }, Schwartzian => sub { () = map $_->[0], sort { $a->[1] <=> $b->[1] } map [ $_, -M ], @files; }, }, ); </code> <p>And that's it. Note that I always use sub refs with [cpan://Benchmark], so the package issues don't even come up. You could assign to an actual array if you don't feel like explaining the <tt>() = ..</tt> construct, but it wouldn't make an appreciable difference in the code.</p> <div class="pmsig pmsig-114691"> <p align="right"><em>Makeshifts last the longest.</em></p> </div> 393128 393128
