Zip Lists groups the first item from every input list, then the second item
from every list, and so on. The result is as long as the longest input; missing
positions become null.
When naming is enabled, every list entry has a Key and List input. Each
output item is an object whose properties use those keys.
Output
Zipping [1, 2] and ["a"] returns [[1, "a"], [2, null]].
Naming the same lists id and label returns
[{"id": 1, "label": "a"}, {"id": 2, "label": null}].
Toggling Name Lists with Object Keys replaces the list-input shape and
changes each output item from a list to an object. Check downstream
connections after changing it.
