    Description

      It would be useful to have a compute function that takes a ListArray<list<type>> and an integer index n and returns an Array<type> containing the n th item from each list.

      This would be useful in combination with existing functions that return list-type output, for example the string splitting functions.

      Let's please ensure that this also works on fixed size list.
