Greetings monks,

I was using Perl 5.8, and recently switched to perl 5.12 ( which comes default on suse 11.3). While browsing for regular expressions, i got some issues while converting regular expression from 5.8 to equivalent in 5.10, below is my working code.

use strict;
use Data::Dumper;

my %hash=();
my $str="Test Tester Testing [Feb 18: 28_10_10] Test";
#my $reg='(?<fname>\w+\b)\s(?<mname>\w+)\s(?<lname>\w+\s).*\]\k<fname>
+';
#my $reg='(\w+)\s(\w+)\s(\w+).*?\[(.*?)\]$1';
my $reg='(\w+) (\w+) (\w+) \[([\w\W]+)\] (.*?)';
{
#    use re 'debug';
    if($str =~ /$reg/is) {
#        %hash=%+;
        $hash{fname}=$1;
        $hash{mname}=$2;
        $hash{lname}=$3;
        $hash{date}=$4;
#       %hash=%+;
    }
}
print Dumper \%hash;

I am trying
#my $reg='(?<fname>\w+\b)\s(?<mname>\w+)\s(?<lname>\w+\s).*\]\k<fname>';

in 5.10, and that seems to be not working :( ...
Can anybody point me what i am doing wrong... !!!

Thanks,
Shekar
