  1. Allow NewType subclassing NewType. 

    Use case: type hierarchy of IDs, all of which are integers at runtime, but we
want to type-check distinctions between e.g. "id of User" and "id of Media",
while still allowing some functions to take "any ID" (which is still a more
specific type than "any integer").
