This issue suggests adding support for a way to iterate multiple sets of fields at different levels simultaneously with the same indexer, effectively a "respectively" approach. For example, normally /{A,B}/{X,Y} would resolve to [/A/X, /A/Y; /B/X, /B/Y]. There is currently no mechanism to resolve to [/A/X; /B/Y] without manually doing it. A good way to do this has not been determined, and no firm proposal is put forward in this issue. A named argument could be provided, or syntax could be modified, though it should be possible to have a "respective" association without dimension association (unlike in #20). Either approach will be similarly complicated as #20 for reasons described in that issue.

Is there a valid use case for this? A realistic example could help.
