True, however, there are different reasons why I dislike having such a
class/type-based constant as a has field:
1. One can mutate it in the instance (including at run-time) by assigning to
$self->{_bold_tag_name}.
2. A more philosophical reason (and more major) is that I feel that "has()"
fields, which are stored inside the object's instance are *instance-based
data* while what I'm looking for is global class/subclass-based data and
constants.
As a result, I think I'll go with my original way, but maybe use "required ''"
to make sure such a method is defined in the non-abstract and production-ready
subclasses.
