Very clever and interesting. Reading and writing Postscript always twists by brain in a particular way. Having written web servers in a number of languages, particularly in Scheme, which twists in another, contrasting direction, even though I'm pretty used to it by now. It's kind of like clockwise and counterclockwise squeezing the neurons until they protest. My head spins. But maybe PS is destined to always take us for a wild ride.
