AOP, aka multiple inheritance?
Rickard’s recent descriptions of his activities in AOP have been very interesting. From my (probably flawed) understanding, it seems that the runtime behaviour extension framework he talks about bears a striking resemblance to an implementation of multiple inheritance. Even more cool than that, a dynamic, runtime adjustable form of multiple inheritance.
We like that.
In an alternative view, it almost resembles a return to modular, function based programming, where cross-cutting behaviour (such as logging) is encapsulated in a single location, and applied everywhere the application requires it. Interesting.
