This is just simple recommendation for you to use PHP 5.3.3 rules
There is too many performance and ability improves in new version of PHP like Namespaces and more ..
I think there is one change that you should pay attention today for future Codeigniter and this is Constructor !
In PHP 5.3.3 methods with the same name as the last element of a namespaced class name will no longer be treated as constructor.
This is better for you to use __construct instead of today CI user guide that tell you to create method function with same name of class ( on Models, Libraries etc.. ).
If you use __construct in CI future changes you just update your CI files and you dont need edit your code.
CI support __construct in current version and you can use it today.
