I have an array ref of hash refs: 
[
  {
            'time_of_request' => '2009-03-12 16:07:13',
            'runmode' => 'authen_dummy_redirect',
            'people_id' => '6877'
          },
          {
            'time_of_request' => '2009-03-12 16:07:14',
            'runmode' => 'affiliates',
            'people_id' => '6877'
          },
          {
            'time_of_request' => '2009-03-12 16:24:25',
            'runmode' => 'affiliates',
            'people_id' => '6877'
          },
          {
            'time_of_request' => '2009-03-12 16:24:45',
            'runmode' => 'agents',
            'people_id' => '6877'
          }
        ];

That I want to reformat with an arbitrary key.. let's say 'people_id': 
{
  6877 => [
           {
            'time_of_request' => '2009-03-12 16:07:14',
            'runmode' => 'affiliates',
          },
          {
            'time_of_request' => '2009-03-12 16:24:25',
            'runmode' => 'affiliates',
          },
          {
            'time_of_request' => '2009-03-12 16:24:45',
            'runmode' => 'agents',
          }
         ]
   4211 => [ ... ],
}

I know that I could write something to do this, but was hoping for a CPAN goodie, the functional inverse of Data::Hash::Flatten.
