Registering the same function twice using the old domainEventRegister()
interface would not work, as the function reference is used for
un-registering.

But it is not a problem with the new interface domainEventRegisterAn(),
as that returns a unique ID.

While at it also demonstrate the 'opaque' mechanism.
