I start out with this:

use vars qw($Pua $parsor $spp_Array);
$Pua = new LWP::UserAgent;
$spp_Array = 0;
$parsor = HTML::LinkExtor->new(\&callback);
my $res = $Pua->request(HTTP::Request->
          new(GET => $WebPage),sub {$parsor->parse($_[0])});
$Ubase = $res->base;


sub callback {
 my($tag, %attr) = @_ ;
 my $Urray = ($spp_Array)? \@main::morePicpages : \@main::Picpages;
 return if $tag ne 'a';
 push(@$Urray, values %attr);
}





This works great once. Then much further down into my code, based all sorts
of conditional stuff far too lengthy to post here, I try this:




my ($all_links, $response, $parser_agin);




$spp_Array = 1;

$parsor_agin = HTML::LinkExtor->new(\&callback);
$response = $Pua->request(
        HTTP::Request->new(
                GET => $all_links, sub {$parsor_agin->parse($_[0])})
                               );








This is how that code fails:


Can't call method "clone" on unblessed reference at D:\perl\site\lib/HTTP/Message.pm line 53.




Help. Cannot see why it worked once then will not work again, and
there's a suspicion in my mind that some OO thing that I don't get
is biting me. BTW, pls remember if you would reply that lots of
perlers don't totally grasp OO, and this is not a pissing contest
but each of us individually on a long-term path of seeking to improve
our depth of understanding. In that spirit, and not merely out of 
individual thin-skinned-ness, flame-like replies will be ignored.

 Thanks
