You might want to submit your report along with a recommended patch, if you want to get it implemented quicker.

I second that, whole-heartedly. In fact, here's my suggestion for a better version (hoping I understand the intent correctly):

sub raw_fetch { my $class = shift; my $raw_cookie = get_raw_cookie(@_) or return; my %results; $raw_cookie =~ s/^\s+//; $raw_cookie =~ s/\s+$//; my(@pairs) = split(/\s*;\s*/,$raw_cookie); foreach (@pairs) { my ($key,$val) = (/^([^=]+)=?(.*)/); $results{$key} = $val; } return \%results unless wantarray; return %results; }
I've only tested it to the extent that the assignments to %results match the original code (except for the trailing whitespace glitch) -- that is, a "raw_cookie" string like this:
one=1 ;two=2; three=the third ; four=  ; five  ; six = the sixth ;
produces these key/value pairs:
'one'=>'1',
'two'=>'2',
'three'=>'the third',
'four'=>'',
'five'=>'',
'six '=>' the sixth'
(note that spaces next to "=" are not deleted)
