 script described at:

 Not only will that give you the very latest version of this rapidly
 changing project, it will be much easier than get GNOME Shell and

-   described at http://wiki.ecmascript.org/doku.php?id=harmony:simple_maps_and_sets,
-   without requiring more than ES5 + Gjs extensions.
-
-   Known differences from other implementations:
-   Polyfills around the web usually implement HashMaps for
-   primitive values and reversed WeakMaps for object keys,
-   but we want real maps with real O(1) semantics in all cases,
-   and the easiest way is to have different hashers for different
-   types.
-
-   Known differences from the ES6 specification:
-   - Map is a Lang.Class, not a ES6 class, so inheritance,
-     prototype, sealing, etc. work differently.
-   - items(), keys() and values() don't return iterators,
-     they return actual arrays, so they incur a full copy everytime
-     they're called, and they don't see changes if you mutate
-     the table while iterating
-     (admittedly, the ES6 spec is a bit unclear on this, and
-     the reference code would just blow up)
