Very helpful and I love you did a VDO too! Smooth and elegant presentation. I'm an APL-trained programmer always seeking brevity. My lines might be (untested!):

use feature "say"; use Filesys::DiskUsage qw/du/'

die "Usage: $0 DIRs\n" unless @ARGV; my %sizes = du({'make-hash' => 1}, @ARGV); say "$_ : $sizes{$_}" for sort { $sizes{$a} <=> $sizes{$b} } keys %sizes;

As an aside- seems difficult to install Filesys::DiskUsage . CPAN install fails.
