Well, it's "better" in the sense that it doesn't match on a sequence of digits thrown together from a couple of handful of different scripts. But I posted it mainly to point you to the `Regexp::Common` module. Useful if you need patterns for common tasks, but you aren't able to write them yourself without asking on the internet.
