It wasn't - the implication is that out of all the optimizations the exist in the world, it's likely that if we ever have ones that are prohibitively expensive to run interactive - they'd most probably be around JIT or other types of native compilation strategies. What you said is the reverse - that JIT optimizations are inherently prohibitively expensive to run interactively, which we obviously all agree on isn't the case and not what I meant. X -> Y doesn't mean Y -> X... Thanks, Zeev -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
