This is not about ordering of elements. One of the key properties of mappings is that they do not lose elements (assuming that the function used for mapping is total, i.e. it always produces an answer). The folding-based approach does not exclude this possibility. For example, it can turn the elements of the list into any other data structure, even some scalar, or exclude elements from the input. It may take a while for the reader to see that it is just about extending the indexes with their prefixes and prefix differences on the field ranges. -- This is an automated message from the Apache Git Service.
