Good work - results more or less confirmed here.

Might be good to submit that script with an enhancement request in the 
bug DB to see if those use cases can be optimized.  Previous requests 
with other commands and functions yielded good opportunities for speed 
boosts, bringing v8 much closer to v6.  Whether the same can be done 
with the language features used here is something I don't know, but once 
in the queue the team can review and advise.
