It looks to me like the character class is the beginning of a range (the [\w-] bit). I know it isn't, and I know Perl has no problems with this (I just ran a test script to verify that).

But wouldn't it be a little clearer to write the character class as either [-\w] or [\w\-] ? This is really just a formatting question more than anything else.
