Note: it would be easier to support arbitrary lambdas if lambda signature was changed from taking a key and 2 values to taking a key and an array of at least 2 values.
Current: (k, v1, v2) -> v
Preferred: (k, array(v)) -> v, where input array is guaranteed to have at least 2 entries and the order of entries in the array matches the order in which they appear in the input string.
