Actually, yeah, you're right... I should've used Symbol('name') instead. My bad! I'll fix the examples.

In the case of the classes lookup, you might have to have some mapping between the value of the $type property and the actual classname if they happen to not coincide. But really, there's no reason to pick Map over an object if you're just mapping strings to objects. I just like to use Map instead of POJOs as hashmaps when they become highly polymorphic, as it doesn't create hidden classes on mutation.
