This is an important point. A provisional idea that preserves our desire to not introduce new features to promises themselves, requiring user choice at authoring time, might be some kind of `console.unhandledRejections()` function which returns you a snapshot of the current unhandled rejections bucket.

I find these kind of things confusing. RSVP did something similar, introducing

RSVP.rethrow = r => setImmediate(() => throw r);

so that you write

somePromise.then(...).catch(RSVP.rethrow); // actually RSVP uses `fail`.

It's not clear to me why this, or your `Promise.throw`, is better than

// or
