final case classObserverKey[S <: stm.Sys[S]] extends Selector[S] with Product with Serializable
Instances of ObserverKey are provided by methods in Txn, when a live Observer is registered. Since
the observing function is not persisted, the slot will be used for lookup (again through the transaction)
of the reacting function during the first reaction gathering phase of event propagation.
