Here is an alternative.

#!/usr/bin/perl -wlT
use strict;
use CGI;
use CGI::ArgChecker;
use Data::Dumper;

my $Q = new CGI;

my $checker = new CGI::ArgChecker;

$checker->register_check('BloT',
sub {
warn "You *really* are a GENIUS!!! @_";
return 1;
});

$checker->error_handler(
sub {
warn "You are a GENIUS!!! @_";
});
 

my $chuck = $checker->argcheck( $Q,
                    'a' => [ 'disallow_empty', 'want_int' ],
                    'b' => [ 'disallow_empty', 'BloT' ],
                  ,);

print Dumper $chuck;

What can I say, I feel *smart* today `.) (btw, CGI::ArgChecker is a wrapper around String::Checker
