You may include some hash map implementations from the dub repo
in your benchmark.

I have tried emsi_containers, memutils and ikod-containers.

default D's AA take 1s on my pc

emsi_containers take 3s realy slow

memutils was fast but does not realy work (seems it is broken because there has been nan at d[0] and many other indexes)

ikod-containers take 242ms
