Yeah, I just don't ever use \d except for one-liners any more. \d now means something that I just never want: numerals of any kind, from any writing system. This despite Perl only knowing how to treat one of the two dozenish types of numerals as numeric. I think drastically changing the definition of \d when Unicode came along was a mistake (a separate way of saying "any numeral" should have been used).
Luckily, the somewhat longer [0-9] has some visual advantages. So the worst problem is all of the old scripts that are now broken in ways that will often not matter (but that I can see even causing security problems in rare cases).
