It occured to me that in my years of programming perl, I had only used goto once (to break out of a deep loop) and have never used redo. It is generally agreed that minimzing the number of goto statements helps in understanding the control flow of a program. But am I missing something with redo?

perlfunc says whimsically that redo should be used when the program wants to lie to itself. That quip and the associated code snippet did not seem very compelling. But Larry, may he live forever, must have seen a clear need for redo.

What uses do you find for redo in your code?
