Joining/Merging AoA

Hi Guys,

I have a little complicated problem...

I have two arrays

@[EMAIL PROTECTED]
 = ( ['id', 'name', 'age'],
           ['1', 'Fred', '24'],
           ['2', 'Frank', '42'],
         );

@[EMAIL PROTECTED]
 = ( ['id', 'sex'],
           ['1', 'm' ],
           ['2', 'm'],
         );

I want to join these two AoA, based on id, so the resulting array will
look like this

@[EMAIL PROTECTED]
 = ( ['id', 'name', 'age', 'sex'],
           ['1', 'Fred', '24', 'm' ],
           ['2', 'Frank', '42', 'm'],
         );

Any Ideas?

Thanks in advance.
