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
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. :)
