That sounds right to me too. But it would be a worthwhile experiment to<br class="">
set up a test to confirm it. Maybe take one or more methods that call<br class="">
numbered primitives, and recode them to call the primitives by name. Then<br class="">
measure and see if anything got slower.<br class="">
