You started by claiming that Azul is more advanced. You got snark. Maybe it’s more advanced at collecting garbage or supporting threads, but it is not comparable in the field of type inference, because Azul’s VM and other JVMs do not do any of the kind of type inference described in this post. And no, invokedynamic is nothing like inline caching for JS - not even close. Most of this post is about what type inference for dynamic languages really looks like when you invest HotSpot-like efforts to that specific problem. Saying that Azul is more advanced at type inference is far off from the truth at a very fundamental level. So I gave you snark. Being snarky is fun sometimes!
