This isn't necessary, because we always return a singleton instance, so
it'll always be initialized by definition.

We can use the class definition object itself as the type. It's
ultimately a pointer to a table object that lasts for the lifetime of
the program (created via the require() call), so therefore we can use it
as a stable ID for the type!
