    Highlight the box below if you want to see the answer...
    [0-z] contains the :;<=>?@[\]^` characters but \w dosen't. Also \w might contain other characters depending on your locale and whether you're using Unicode or not.

    update: Answer despoiled in the spirit of quizing...

    [0-z] matches all ASCII characters between ordinals 48 and 122. This includes alot of symbols that aren't in the set matched by \w, which only includes letters, numbers, and the underscore [a-zA-Z0-9_].
