Sure, thing. But PICs are not permanent (and interpreter doesn't have them). With cache you can avoid like 85%? of cases.. but for 15% VM still does lookup. And all caches tend to be flushed periodically.. And then you pay the price of bloated method dictionary :) > Cheers, > Henry -- Best regards, Igor Stasenko.
