just curious about changes in 2.3.x code

G'day,

Just been surfin the code and wondered,

1) Why the changes from [not] equal to ---> [not] identical to ( != | == ---> !== | === )
   (many examples throughout code in 2.3.0 ---> 2.3.2: Utility\Debugger.php, Routing\Router.php, Network\CakeRequest.php, etc)

2) Why the changes to drop return by reference ( &function() ---> funcion() )
   (many examples throughout code in 2.3.2 ---> 2.3.4, eg: getInstance( . . . ) in Utility\ClassRegistry.php, Utility\Debugger.php, I18n\I18n.php, etc)

Thanx, McS
