Hello, I'm new to perl, but not programing. I'm playing with fetching data from web pages. I have a simple program: 
    use warnings;
    use LWP::Simple;
    
    my $url = 'http://example.com';

    my ($t1, $t2, $t3, $t4, $t5)=head($url) or die 'Unable to get page
+';
    my $temp = head($url) or die 'Unable to get page';
    print Dumper($temp,$t1, $t2, $t3, $t4, $t5);
    print "done\n";
    exit 0;

Note, this question is about the particular code snippet, but even more it is about understanding variables in Perl. I used $t1 - $t5 because the documentation said that head() returns a list. $temp contains a lot of information, $t1, - $t5 contain only a very little. How would I get something like the return code (_rc) or the etag header, or the user agent? My first instinct (which seems to be wrong) would be to treat this like an associative array and try 
 
$temp['headers']['etag'] 
and
$temp['_rc']
and
$temp['_request']['_headers']['user-agent']

I would like to understand this. Any help would be appreciated.
