We'd use runtime typeinfo. > The easy thing to do is to use GC locally (like for a fiber) and use > move semantics for moving objects from one locality to the other > (between fibers). Though it's challenging to efficiently manage all the GC structures for a small scope. Doing this per thread is a proven technology (see https://trello.com/c/K7HrSnwo/28-thread-cache-for-gc).
