Thanks Ben The left-pad example is most helpful. Perhaps it could be included in the docs, given that usefully illustrates features of ->i for which no example is given.
I may well have a shot at re-implementing it once I have sufficient machinery set up to support multiple and optional arguments in the kind of style I favor for expressing contracts. Then it will be interesting to see how the readability compares. Thanks also for pointing me to the paper on contracts — time for a re-read!
