Maybe you don't need to tie an anonymous hash:
use strict;
use warnings;
use Tie::IxHash;
use Data::Dumper;
my %big_hash = (
'part_1' => tie_me_up(first => 1, second => 2, third => 3),
'part_2' => tie_me_up(foo => 1, bar => 2, baz => 3),
'part_3' => tie_me_up(oranges => 1, apples => 2, lemons => 3),
);
print Dumper(\%big_hash);
sub tie_me_up
{
tie my %temp, 'Tie::IxHash';
%temp = @_;
return \%temp;
}
Output:
$VAR1 = {
'part_2' => {
'foo' => '1',
'bar' => '2',
'baz' => '3'
},
'part_3' => {
'oranges' => '1',
'apples' => '2',
'lemons' => '3'
},
'part_1' => {
'first' => '1',
'second' => '2',
'third' => '3'
}
};
