That's what he said they did. that's the joke. >so they changed the existing code to just check that predicate first, and the code sped up a zillion times, much more than with Ken's solution. but since you've now spent all this time developing some beautiful solution for .01% of the actual data flow. Not the best use of dev time, essentially.
