Move copies an iterator. The copied iterator can come from any row in the target path. It is possible to take a relation that is nested in an outer row and nest a copy of it into every row in a deeper relation. Unlike Dup, the copied iterator shares state with the original one. It is illegal to iterate over one iterator in an inner loop while maintaining the context of the other in an outer loop.
