Well yesterday I wrote a handler for DateTime (actually 
DateTime::Format::ISO8601). When you pass it an invalid date DT says 
things like:

   The 'month' parameter ("21") to DateTime::new did not pass the
   'is between 1 and 12' callback

which I think would be more helpful to the user than CGI::Untaint's:

   time_of_record (1999-21-22) does not pass the is_valid() check
