Based on ES6 keywords: [msn docs](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Lexical_gr...) and [ES6 specification](http://www.ecma-international.org/ecma-262/6.0/#sec-keywords).
I did a second 'amend' commit to remove `each` from primary since I didn't find anywhere it's keyworded. You can view, comment on, or merge this pull request online at:
