In your specific case, where you want every last inch of performance, it is acceptable that you will need to use the optimized idiom. However, if your overall code did anything else besides banging hard against your algorithm, a performance say 5 times worse than Java may soon become acceptable. In my case, for example, I managed to get the time low enough to be drowned out by index reading times inside Lucene. If I could have achieved that without involving arrays, loops, and defrecords, I wouldn't have a reason to complain.
