Hello monks,

What are the pros and cons of using multidimensional hash emulation compared to using hash of hashes?

Consider the following code: 

%the_hash = (
  empl_john_id => 13,
  empl_john_position => slave,
  empl_bob_id => 0,
  empl_bob_position => manager,
  client_fred_id => 2,
  client_fred_phone => 12345,
  client_goldman_id => 0,
  client_goldman_phone => 666
);

%the_hash2 = (
  empl => {
     john => {
       id => 13,
       position => slave
     },
     bob => {
       id => 0,
       position => manager
     }
  },
  client => {
     fred => {
       id => 2,
       phone => 12345
     },
     goldman => {
       id => 0,
       phone => 666
     }
  }
}

Will %the_hash2 work faster for fetch/store operations.

Is there a generalized rule on this TIMTOWDI?

Thanks
