       Initial development of this policy was supported by a grant from the Perl Foundation.

       This policy is not for everyone!  If you are working in pure ASCII, then disable it now or you may see
       some false violations.

       On the other hand many of us are working in a multilingual world with an extended character set, probably
       Unicode.  In that world, patterns like "m/[A-Z]/" can be a source of bugs when you really meant
       "m/\p{IsUpper}/".  This policy catches a selection of possible incorrect character class usage.

       Specifically, the patterns are:

       "[\t\r\n\f\]" vs. "\s""[\t\r\n\]" vs. "\s"   (because many people forget "\f")

       "[A-Za-z0-9_]" vs. "\w""[A-Za-z]" vs. "\p{IsAlphabetic}""[A-Z]" vs. "\p{IsUpper}""[a-z]" vs. "\p{IsLower}""[0-9]" vs. "\d""[^\w]" vs. "\W""[^\s]" vs. "\S"

       of explicit character lists.
