[We had a short twitter chat .. you mentioned it'd be good to have longer one.] Both babel and traceur have two workflows: static & dynamic. Static transpiles the es6...

Now that [ES2016](http://www.2ality.com/2016/01/ecmascript-2016.html) is out, are there plans for including these feature in your browser tests?

`ArrayMethods` isn't particularly useful to me. However, an exact report of which methods passed and failed would be wonderful. The design I think would be amazing is (using "supports" as...

The [module tests](https://github.com/getify/es-feature-tests/blob/ab31cd45ef6ffcaef4877e422e22ecd3877f985f/lib/featuretests.js#L31-L32) don't make sense.

Judging by the use of `Object.keys` and `foreach` I believe IE8 is not supported. Or at least requires polyfills. I'm not sure about old Opera. These still need to be...

For example, [newly added tests](https://github.com/getify/es-feature-tests/issues/10) `letLoop`, `constLoop`, and `letLoopScope` need to have some sort of scan test in `testify`, if possible.

help wanted

Hi, First of all, great project, really appreciate your work and hope babeljs to implement it on some level so we can exclude from transpiling some of the language features...
