I think you can just construct a new object, no need to assign into the parent's
object_template_.

In fact the only thing we're using is NativeHandler's NewInstance method.
Perhaps this should be a pure virtual instance, and what NativeHandler is
currently should be like ObjectBackedNativeHandler or something.

I agree, I'll do it once I get some other stuff figured out.
