ECMAScript 2015 support

[chicoxyzzy]

Any plans on support current version of ECMAScript specification?

Yeah, for now we'd like to focus on completing ECMA5 compliance.

We already started implementing one ES6 syntactical feature:

{
 foo () {
   // ...
 }
}

We'll likely add more and make them available through a build time flag. We don't want to confuse users with partial support. (The ES6 feature highlighted above is currently not conditionally compiled, but IMHO we should)
