To be clear, do you mean that Map/Set is faster than {} even for plain idiomatic hashes with string keys (as opposed to pathological cases)? When I last tested

To be clear, do you mean that Map/Set is faster than {} even for plain idiomatic hashes with string keys (as opposed to pathological cases)? When I last tested in other JS engines I found plain {} hashes were still moderately faster. (Haven't tried Safari since it doesn't support what I've been working on)
