For me, the main question is where this complexity lives. To minimize the places where sharp knives need to be used, I would prefer to move this up into a language runtime and have the VM/engine underneath focus on implementing a simpler object model that has the mechanisms to pull off these tricks without resorting to unsafe tricks.
