There will be some static helpers provided from the SDK. I originally
started the JSNI 2.0 document but it is basically waiting for me to start
on Elemental 2.0 and accumulate more experience to turn it into something
more concrete.

Actually I have new ideas on this derived from how some other APTs work.
I need to update the JsInterop doc but these are the options that I'm
thinking right now:
*Option 1 (works better for extending):*
@JsType(prototype = "Promise")public interface Promise {
/* Protoype_Promise is an autogenerated package visible class */
public static class Prototype extends Protoype_Promise {
public Prototype(Function... functions) {
super(functions);
}
}
void then(Function f);
void cath(Function f);
}
*Option 2 (works better for general use):*
@JsType(prototype = "Promise")public interface Promise {
/* Protoype_Promise is an autogenerated package visible class */
public static Promise create(Function... functions) {
return new Protoype_Promise(functions);
}
void then(Function f);
void cath(Function f);
}
*Of course one can do both:*
@JsType(prototype = "Promise")public interface Promise {
public static class Prototype extends Protoype_Promise {
public Prototype(Function... functions) {
super(functions);
}
}
public static Promise create(Function... functions) {
return new Prototype(functions);
}
void then(Function f);
void cath(Function f);
}

Great work. This kind of stuff is also very valuable as a feedback.
