This splits cached expression by receiver type such that the initializing expression for a cached variable isn't stored in the late variable initializer, if it can be obtained in different ways. For instance having both a list pattern and a map pattern in the same switch will trigger caching of the .length property but obtaining expression differ base on the receiver type, in the first case List.length and in second case Map.length.
