Dear Masters,
Is there a quick way to transform a HoA into AoH like this, from:

my $HoA = {
            flintstones        => [ "fred", "barney" ],
            jetsons            => [ "george", "jane"],
      };

Into:

# Desired result:
my $AoH = [

              {
                flinstones => "fred",
                jetsons    => "george"
              },
              {
                flinstones => "fred",
                jetsons    => "jane"
              },
              {
                flinstones => "barney",
                jetsons    => "george"
              },
              {
                flinstones => "barney",
                jetsons    => "jane"
              },

];

The size of the hash and array in HoA input maybe varying.

Update: Correction made on the correct data structure of the desired results, thanks to pg comments.

Update 2: The actual HoA in my production code looks like this:

my $HoA = {
            '1,2,flintstones' => [ "fred-1 foo-2", "barney-1 bar-2" ],
            '2,3,jetsons'   => [ "george-1 foo-2", "jane-1 bar-2"],
      };

Update 3:Additional examples:

With array of only one element

my $HoA3 = {
            'flintstones'    => [ "fred" ],
            'jetsons'        => [ "george"],
      };

my $ans3= [
          {
            'flintstones' => 'fred',
            'jetsons' => 'george'
          }
        ];
[download]

With array of differing size:

my $HoA4 = {
            'flintstones'    => [ "fred" ],
            'jetsons'        => [ "george","jane"],
      };

my $ans4 = [
          {
            'flintstones' => 'fred',
            'jetsons' => 'george'
          },
          {
            'flintstones' => 'fred',
            'jetsons' => 'jane'
          }
        ];

Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
