You know, I've been waiting since before the original release of Date::Holidays::UK (which CPAN has down as the 16th March) for this bug report.
I'm especially gratified to find that my pedant thinks I don't know that the regions holidays are defined in are "England and Wales", "Scotland", and "Northern Ireland", and so needed it all explaining to me.
Unfortunately, now that it's arrived, I'm still having trouble caring.
Still, I remain thankful that it's not code for correctly formatting telephone numbers.
