In addition to liking my 84-character-width gvim windows (to allow a little leeway) side-by-side for code references, I'm definitely not above printing out some code to lay it out on a desk---that's not something you can do on-screen without a wall of monitors in front of you. The only time I regularly break my rule is for regular expressions (at some point I may embrace re.X to allow me to break those up, too). All the best, Jason
