Just give the text (reasonably) straight-forward (like Dominus does here) because no-one can figure out what you're doing with it anyway :)

To me, this is the heart of obfu -- find some interesting or unexpected Perl behavior, and use it as the core of the obfu. Sure you can uuencode your text, or replace all the variables with punctuation vars, but for taking the time to unravel these things, the reader deserves to be rewarded with some nugget of "aha".
