[Discuss] for loop metaphor

[Karin Lagesen]

The more I teach, the more I realize that I am not really able to convey 
what a for loop does to everybody. Do any of you have a metaphor or 
something that you use for teaching it? I explain about variables and 
collections, and the body of the loop, and I show examples, but I am 
still not able to get through all the time.
