What should be optimized for?
It depends on the relative slowdowns, possibly.
And to be clear, all I was pointing out is that the speedup from
treating numbered properties specially is very noticeable and appears on
real-life workloads. Where we go from there is a separate issue.
Note that we don't really even have to choose. If you tell the guys
implementing these crypto / bignum libraries that their code is going to
run 6x faster in Firefox if they use an Array, they'll probably have
switched by Tuesday.
I told them in September. There's been no change yet. I think you
overestimate how much people are willing to change their code to work
around what they think are bugs....
