The question is whether the speedup comes from the reduction in lookup times or the reduction in string copying. I have a strong suspicion that it's mostly the first, not the second.
Agree with about Oleg's test, but some users put huge values into json... Actually, I don't insist, ITSM, that's easy way to prevent extra copying.
