Perl challenge

Perl is beautiful
It's just that usually people use Perl for some quick reg ex hacks and just throw some ugly code together fast to get the job done. So people just Perl on this.

Perl gives you the option to code however you want. I challenge you to post Perl code that cannot be made beautiful.

I would use them on copies of the array, but who uses temporary variables?

I don't understand why Perl would make me use temporary variable when no other programming language has ever required the use of temporary variables for any task at all.
