 * ### `subscribeState` helper
 *
 * Note: I'm using "closed" & "unsubscribed" interchangeably below.
 *
 * Helper provides your next function another subscription which will be closed each time obs emits.
 *
 * This is especially useful for creating nesting subscribers that should be closed anytime there is a new emission.
 *
 * This is common when subscribing to a "state" or "view" observable, because each `next` emitted value
 * essentially means that everything dependent on the previous value should be disposed of (closed / unsubscribed),
 * hence the name `subscribeState`.
