Define 'widely used' and 'is it necessary' ;-) I would say, from the point of view of an Aspects guy (me), that a noticeable influence in the acceptance of the language AspectJ is that they have an acceptable level of IDE support. And there is no escaping the fact that sometimes the decomposition of the system will lead to code that is scattered around different places. Single inheritance with objects is not a silver bullet. But it can be 'good enough' … worse is better ...
