Hmm, that has appeal. If you assign a partition to a list of arrays, 0/false selected go into the first, number goes into the n'th, with the last also getting numbers that are too big and strings that are true. But it could instead be assigned to pairs, and the partition block selects a key or default which chooses the target. --
