Dear BrowserUk,
Thanks so much BrowserUk. But with your dataset example above it should give this result instead: 
$VAR1 = [
          {
            'flintstones' => 'fred',
            'jetsons' => 'george',
            'domo' => 'harry'
          },
          {
            'flintstones' => 'fred',
            'jetsons' => 'george',
            'domo' => 'gatou'
          },
          {
            'flintstones' => 'barney',
            'jetsons' => 'george',
            'domo' => 'harry'
          },
          {
            'flintstones' => 'barney',
            'jetsons' => 'george',
            'domo' => 'gatou'
          },
          {
            'flintstones' => 'fred',
            'jetsons' => 'jane',
            'domo' => 'harry'
          },
          {
            'flintstones' => 'fred',
            'jetsons' => 'jane',
            'domo' => 'gatou'
          },
          {
            'flintstones' => 'barney',
            'jetsons' => 'jane',
            'domo' => 'harry'
          },
          {
            'flintstones' => 'barney',
            'jetsons' => 'jane',
            'domo' => 'gatou'
          }
        ];

So the size of individual size of hash must be the same with initial size of HoA.
