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