Well, that depends on what you want to do with the data. Generally, I pull a number out of a string because I want to do math with it, but Perl only does math with characters "0" .. "9", other characters get turned into 0. This has made \d next to useless for me as I am looking for a number and it can return a string. The other problem is that for years people have been saying "don't use [0-9], use \d instead", so now we have to say just as loudly and often "Only use \d if you mean any UNICODE character that is marked as a digit and use [0-9] when you want to do math on the result" (which is what I am doing). -- Chas.
