Surely the Adobe fellows have something to say about this :). Flash

ES4 has new syntax;

Besides compatibility issues, this would be a significant performance
regression for math-heavy code. I would consider this a showstopper to
implementing such a change.
I'm inclined to agree that it is (unfortunately) probably not a good idea

Subject: ES3.1 Proposal Working Draft
Each of us has some pet addition we think would be a great addition to
the language. const, decimal, getters and setters, destructing
assignment -- all these have come up just this morning!. Each of these
makes the language larger and more complex, imposing a general diffuse
cost on everyone.

Mark, as I recall, the discussion at the March meeting in Newton involved
implementing decimal arithmetic in ES3.1 to *replace* the floating point
implementation in ES3, thus no new syntax. Yes, this would have unexpected
results for those who actually
