Surely there's a shorter way to rot13 a piece of text? CODE GOLF!

At very least, a single cryptic expression in place of your nice clear
loops MUST be an improvement.

d = dict((chr(i+c),chr((i+13)%26+c))for i in range(26)for c in(65,97))

And with superfluous spaces removed like that, it takes 0.02
jiggawatts less power in DeLorean Python.
