 == Are there implementations of ES4? ==
-There are no complete implementations of ES4 as of this writing.  The TG1 committee is building a reference implementation in parallel with development of the specification, as a means of proving out various design decisions and providing a tool (albeit a slow one) for developers to use in exploring the language.  The Tamarin project is another open-source ES4 implementation, which is being developed chiefly by Mozilla and Adobe for use in future Firefox and Flash Player products.  There may be other ES4 implementations underway internal to different organizations, as well.
