It would be easy to create a "moments_reader" that does calculations
like this as side effects and otherwise passes cases through
without modification.
There would be no need to make this part of sorting. Just make a
"moments_reader" out of your data and then pass the
moments_reader to sort_execute.Thanks for the suggestion. I'll look into it. J' -- PGP Public key ID: 1024D/2DE827B3 fingerprint = 8797 A26D 0854 2EAB 0285 A290 8A67 719C 2DE8 27B3 See http://pgp.mit.edu or any PGP keyserver for public key.
