ZoneAwarePromise vs disambiguate_properties (type aware optimization)

[mprobst]

Angular 2 uses Zone JS, which re-implements Promise, including "static" functions like Promise.all. This does not seem to play well with --disambiguate_properties and --ambiguate_properties. Closure removes the .all implementation, Zone still patches the global Promise object, and then user code fails when it calls Promise.all as the function is no longer present.

I'm not sure what the best fix is, or if this is something tsickle can handle at all. Currently the tsickle-with-types emitted code doesn't even @implements Promise or IThenable, but even if so, I would presume the "static" method would be removed, as Closure doesn't understand inheriting static properties?
