Not so pretty but: import * as global from “@global”; Or some bindings: import {Promise} from “@global”;

Miller; es-discuss@mozilla.org Subject: Re: Putting `global` reference in specs This is one of several cases where, post ES6, we can provide a std module import that provides a built-in that carries authority. Another example is the constructor for making weak references, which necessarily provide the ability to read a covert channel. As with shadowable globals, this module import must be easy to virtualize. We purposely postponed this along with the Loader and Realm API as it is security sensitive and we don't yet have enough usage experience with modules to know how to design this separation well. In particular, we rejected the obvious Reflect.global as it bundles the global together with authority-free safe things, which makes virtualization of the global alone needlessly unpleasant.

Since in scripts you can reliably get hold of the global object by using "this" in the root scope. And es 2015 made an explicit choice to clobber "this" in the root scope of a module, I guess that means module code really isn't supposed to get hold of the global object?

For my brain, adding the "use strict"; makes this snippet of code much simpler.
