I want to take an array and turn it into a hash nested as far deep as the number of elements in the array. For example: 
@foo = qw[1 2 3 4 5];

should transform into a hash that looks like this

$bar->{1}{2}{3}{4}{5} = undef;

I have code that works but I'm not terribly happy with it and I know there is some foo I'm missing somewhere. Below is the code I have working: 
use Data::Dumper;
use strict;
use warnings;

my $hashref;
my @foo = qw[1 2 3 4 5];

my $string = "\$hashref->";

foreach    my $item (@foo)
{
    $string .=    "{$item}";
}
$string    .= "= undef";

eval($string);
print Dumper($hashref);

As I said, this works but I feel there is probabbly a much more perlish way to do it. I searched a bunch of different places and didn't find much other than the normal perldsc type stuff.
