Hash slices and reference and seperate issues... Here are two examples of
hash slices, one on a hash and one on a hash reference
#!/usr/bin/perl -w
use strict;
my %normal_hash = ( firstname => "Jeff",
lastname => "Bisbee",
email => '[EMAIL PROTECTED]' );
my $hash_ref = { firstname => "John",
lastname => "Doe",
email => '[EMAIL PROTECTED]' };
my @keys = qw( firstname lastname );
my ($name1,$lastname1) = @normal_hash{@keys}; # normal slice
my ($name2,$lastname2) = @$hash_ref{@keys}; # reference slice
print "$name1 $lastname1\n";
print "$name2 $lastname2\n";
