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