-- A subscribable source must expose `subscribe()`.
-- Returned subscriptions are cleaned up with the owning Solid scope.
+- A subscribable source must expose `subscribe()`, and that subscription may return either a cleanup function or an object with `unsubscribe()`.
+- Emitted values are not deduplicated by equality.
