Atom effect able to get another atom's value

I’ve been looking into atom effects and they look really helpful. In the example, it shows a state synchronization example effect like this:

const syncStorageEffect = userID => ({setSelf, trigger}) => {
  // Subscribe to remote storage changes and update the atom value
  myRemoteStorage.onChange(userID, userInfo => {
    setSelf(userInfo); // Call asynchronously to change value
  });

  // Cleanup remote storage subscription
  return () => {
    myRemoteStorage.onChange(userID, null);
  };
};

That looks perfect, if myRemoteStorage is a static, but how would you structure that same effect when myRemoteStorage is coming from a Recoil value? If the datastore is also tracked in a Recoil atom, then I can’t figure out a good pattern for using it in an effect. Was there an approach in mind to handle that pattern?

@mdlavin - We are exploring the ability for atom effects to look at the state of other atoms, perhaps via providing a mechanism like getSnapshot() as a callback for the atom effect.

also i think it’s a good feature if it possible that in effects_UNSTABLE.onset, update other atom. i want some atom’s effect propagation to other atom’s effect.
