After Break Bonanza: Expading the Nerdom of God

I know this one is usually outside my purview, as i don't usually do the whole programming thing, but i thought i would go ahead and post an XKCD on programming the universe. For those who don't know, LISP and Perl are two computer languages (the code your computer reads and runs). LISP is the great grand-daddy of coding language, developed in 1958, exceedingly complex, very sturdy and logical, and still in use today. Perl on the other hand is much more modern, much more simple, and some would argue, a little more ramshackle. So what would god write the universe in?

For once i get to say this one is not from SMBC, but instead all credit and rights go to Randall Munroe at XKCD.com
