Another option to consider: Treat the problem as a `reduce` on the sequence of adjustments where the processing of each adjustment depends on the user input and "cancel" makes the processing return (reduced nil) to halt the reduction. That will stop automatically when the sequence of adjustments ends or the processing function evaluates to a reduced value.
