"Have a good time"

[mgaudet]

While writing up a related specification bug I re-read the Type IV subclassing section multiple times.

As a reader, I find myself the phrase "have a good time" to be vague and non-specific. There's a hand-wave here that would be nice to clarify. When someone isn't 'having a good time', what is the specific bad outcome? Is it that the specification is inconsistent here, and has bugs that need to be worked around (my issue suggests yes!) or is it more that the specification support for subclassing around regexp is incomplete, and requires more work than one would reasonably expect?

Both are true, but I think the verbiage ought to be clarified.

I think the example needs clarified, because it's unclear what the bad behavior is. The bad outcome implied refers not to the spec, but to the users of a given subclass.
