want to try ECMAScript 4?

if you just can't wait for ECMAScript 4 (aka the next version of ActionScript and JavaScript) to be implemented in Flash Player and Web browsers, you can already experiment with it today using the ECMAScript 4 Reference Implementation.

the Reference Implementation is actually very easy to set up and use. to get started with it, watch John Resig's short video explaining basics of installation, and compiling and running programs.

of course, the Reference Implementation doesn't include the Flash Player API or a Web browser API (e.g., the DOM), so you can't actually create any visuals with your code, but you can try out the new core language features, such as block scope (let), multimethods/method overloading (generic functions), and iterators.
