I'm wondering, perhaps the undetermined period a feature can be deprecated
isn't the best idea. Perhaps when we deprecate a feature, we should also
determine when the feature will be deleted. This can even be shown in
the error message:

    %s is deprecated and will no longer be available in perl 5.30 or beyond.
