ES 3.1 implementations?

[Robert Sayre]

I am putting together feedback on the JSON features proposed for ES
3.1, and I was wondering if there any ES 3.1 implementations
available.

Given the limited scope of the spec, I would expect to see at least
one implementation completed soon if there isn't one. Maybe in Rhino
or something?
