Tie::ListKeyedHash

Allows the use of array references as the keys to hashes. 

Like this: 
      $hash{['key','items','live']} = 'Hello!';

or
     
      $hash{'key','items','live'} = 'Hello!';

To install:

perl Makefile.PL
make
make test
make install

Alternatively, if you have Module::Build installed,

perl Build.PL
./Build
./Build test
./Build install
