I wasn't suggesting you should write "[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]" in Perl — sure you can generate the pattern any way you like :)

I just meant to point out that globbing itself provides no means to say "10 times" a subpattern (like {10} in regex); you have to specify the pattern "unrolled" instead.
