You guys are talking about referencing the global object in modules right? 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?
