Hi.

The easiest solution is to remember that Tie::IxHash is just a normal class under the "tie" scenes. Yes, it defined a few "magic" methods (FETCH, STORE, etc), but it is still just a variable blessed into a class. You can use this property to create a Tie::IxHash object, freeze this object with Data::Dumper, then used the thawed Tie::IxHash object to create a new tied hash.

Something like this:

#!perl

use strict;
use warnings;
use Data::Dumper qw(Dumper);
use Tie::IxHash;

tie (my %x, 'Tie::IxHash');

%x = (
    'A' =>  1,
    'B' =>  2,
    'C' =>  3,
);

print join "", (map { "$_ = $x{$_}\n" } keys %x), "\n";

my $x = Tie::IxHash->new(%x);

my $dumped;
{
    local $Data::Dumper::Terse = 1;
    $dumped = Dumper($x);
}
print "Dumper: $dumped\n";

undef $x;

print "\$x is undef\n\n" unless $x;

my $y = eval $dumped;

tie (my %y, 'Tie::IxHash');

@y{$y->Keys} = $y->Values;

print join "", (map { "$_ = $y{$_}\n" } keys %y), "\n";

__END__
A = 1
B = 2
C = 3

Dumper: bless( [
                 {
                   'A' => '0',
                   'C' => '2',
                   'B' => '1'
                 },
                 [
                   'A',
                   'B',
                   'C'
                 ],
                 [
                   '1',
                   '2',
                   '3'
                 ],
                 0
               ], 'Tie::IxHash' )

$x is undef

A = 1
B = 2
C = 3

I hope that this helps.
