+/* This looks like a lot of work at the moment - we're keeping a
+ * duplicate copy of the state up-to-date.
+ *
+ * This can change in two ways:
+ * - With constant state objects we would only need to save a pointer,
+ * not the whole object.
+ * - By adding a callback in the state tracker to re-emit state. The
+ * state tracker knows the current state already and can re-emit it
+ * without additional complexity.
+ *
+ * This works as a proof-of-concept, but a final version will have
+ * lower overheads.
