in reply to Tie a hash of hashes?

This is pretty much exactly what I created Tie::Autotie for.

    Is that module going to work in this situation?

    The module's description on CPAN says it doesn't work when creating a hash reference, which is what I'm doing, isn't it?


    When I try it with this code: 
    use Data::Dumper;
use Tie::Autotie 'Tie::IxHash';
tie %data, 'Tie::IxHash';

  do "File";

  print Dumper \%data;

    I get the following output: 
    $VAR1 = {
          'SomeStuff' => {},
          'SomeMoreStuff' => {}
        };

    Which seems to support the module's description that its not going to work in this situation.

      Tie::IxHash doesn't even work in that situation. The problem is that when you use a hash reference altogether -- that is, $hash{x} = { ... } -- you are creating a hash reference in Perl, and that is not "caught" by Tie::IxHash. You can't achieve the desired goal the way File is set up. You'll need to change it, no matter what you do.
