`this` inside modules

https://gist.github.com/caridy/eefb9b104874465d4e1c#2-whats-the-execution-context-for-a-module seems to indicate `this` will become some sort of module meta object with a variety of abilities: `this.name`, `this.address`, `this.import`, `this.get`, and `this.module`.

This seems like another unfortunate addition to the WTFJS canon, as it continues to add more confusing meanings for `this` to the mix.

IMO it would be much better to leave `this` as `undefined`, just as it is in strict mode scripts, and thus be able to tell a consistent story that in ES6, `this` is about methods. The current proposal would instead create a world where `this` is about methods most of the time, but is a magic ambient variable in some cases (sloppy scripts, modules). This kind of confusion is evident even in the title of that section: it asks "what is the execution context for a module," but it is actually talking about `this`, which has nothing to do with [execution contexts][1].

If a magically in-scope binding is necessary to access module meta capabilities, giving it a name like `module` or `System.currentModule` would be much better.
