I think this would solve an issue I'm facing. I'm working on implementing variations of Monte Carlo tree search for very large trees, with states and actions represented by maps. There are several lookup tables indexed by either state or state-action pairs. I haven't done any detailed benchmarking or perf analysis, but I'm guess that hash/equality consumes no small amount of time.
