Fast Way to Return Unique Array of Array

neversaint has asked for the wisdom of the Perl Monks concerning the following question:

Dear Masters,
I am trying to find unique array of Array with this code:

use List::MoreUtils qw/uniq/;

my @AoA = (['a','b','c'],
           ['a','b','c'],
           ['a','b','d'],
           ['a','b','d']);

my @uAoA = uniq(@AoA);

print Dumper \@uAoA;
[download]

But it fails to return the desired result:

$VAR1 = [
          ['a','b','c],
          ['a','b','d']
        ];
[download]

Why is it? Is there a quick way to achieve that?
