Yes, I too find the "do$0" loop hilarious. A great write-up of its use in the 2002 Kolakoski game by good ol' Rick Klement can be found here and also in Mtv's book of golf (page 105). I believe Ton Hospel was the first person to use the eccentric "do$0" loop in a golf competition. And thanks for the "redo" tip; I'd forgotten about redo after all these years. :)

Update: Just noticed another Rick Klement gem where he concludes with: Lesson to be learned: try something before you say "that can't work" ... which looks like an independent invention of Eugene van der Pijll's famous golfing aphorism: Can't possibly work, let's try it anyway. :)
