Re: ES6 “modes” and user-friendliness

Modules carry the torch of ES5-strict and take it even further, and become the actual "mode" that gets used in practice, both because it is a useful feature independent of the language cleanups in carries with it, and because it doesn't require a noisy opt-in pragma.

One more question: Is there an opt-in strategy should a version after ES.next introduce breaking changes? That might be something worth planning for. Presumably modules will make it easier to encapsulate this kind of change.
