In the 'module', 'bar' is local and 'main' is imported before the module is
evaluated. In 'script' bar is global and the 'main' is imported at the end
of the script. The fate of 'this.foo' hangs in the balance until TC39
speaks.

My point: if 'this' is not global in modules, then ES6 must have an
alternative way to name the global object.
