Iterators

[JonKrone]

Could thunks be turned into generators?

• augment thunk middleware to notice and handle iterators

interface Iterator {
    next(value) : IteratorResult;
    [optional] throw(value) : IteratorResult;
    [optional] return(value) : IteratorResult;
}

interface IteratorResult {
    value : any;
    done : bool;
}

interface AsyncIterator {
    next(value) : Promise<IteratorResult>;
    [optional] throw(value) : Promise<IteratorResult>;
    [optional] return(value) : Promise<IteratorResult>;
}
