This isn't really obfuscation, it's even vaguely useful, but see if you can figure out what Pipes.pm must be doing, given that this prints o-l-l-e-H

use strict;
use warnings;
use Pipes;

print "hello" |
fn { ucfirst($_[0]) } |
fn { [ split('', $_[0]) ] } |
fn { [ reverse(@{$_[0]}) ] } |
fn { join('-', @{$_[0]}) } |
fn { $_[0] . "\n" };
