I have often used
(list1 i. data ) { list2, other
where list1 and list2 have the same shape and "other" is the item
I want to use for the "missing" case.
Of course,
(list1 i. data ) { list2
can also be useful because this would generate an error when data
contains items not in list1.
That said, for your specific example, I would probably use
3 ~:i.5
