var someResourcePromise = sometingAsync.get('someResource'); // this returns a promise which when resolved will return an object { more: { id: 123 } }

var doSomethingAsyncWithResult = function (id) {
  return somethingAsync.get('moreResources', id);
}

someResourcePromise.then(doSomethingAsyncWithResult); // of course doenst work becuase the actual id would be in id.more.id
// is there some way in Q instead of then() to basically extract a property from a previous fulfillment?
// maybe like
someResourcePromise.thenExtract(dosomethingAsyncWithResult, "id.more.id");

// the idea is that the doSomethingAsyncWithResult should be unaware of the structure of the someResourcePromise fulfillment structure
// sure, i could define an actual function inside then() and extract the property and then call somethingAsncy.get('modeResources')
// but that creates lots of little extra functions that could be abstracted away
