The import just has access to the class name, not the
(as-yet-not-created) object.

The fact that the object doesn't exist doesn't matter to the sub being
registered as a callback since it will exist when the callback is run.
But it does matter the add_callback() method itself.
You can never do
$self->add_callback( init => sub {...})
where $self is an object and have that sub get executed. It will only
get executed if $self is a class name.
