Hi, I made the following test script:
use strict; use warnings FATAL => 'all'; use LWP::UserAgent; my $fields; my $ua = LWP::UserAgent->new; my $res = $ua->get( 'http://www.google.com/', %$fields ); This script runs with no errors, although the variable $fields is undefined and it is used as a hash reference and I don't understand why. If I use it in the following line however, it gives the error "Can't use an undefined value as a HASH reference": my %params = %$fields; Does anyone have an explanation why in the first example it works fine?
