Are you just trying to make my head spin?

The targeted positions would incrementally be off by one for each step, which would lead to some pretty crazy logic in a program. It's difficult for me to see how this would be anything but confusing if trying to troubleshoot a program where it was used this way. I'd be more inclined to put placeholders in a list and then use PUT (or PUTI) to replace the placeholders as needed. At least that way there would be a direct correlation to the indices with the final positions in the list.

How would you use this kind of construct? I'll admit it may simply be my lack of imagination for understanding how useful this could be.
