In case you missed it, the Swiz team has made Swiz 2.0 Beta available. It includes the much-anticipated Aspect-Oriented Programming (AOP) features that have been in the works for a long time. AOP is incredibly powerful, and having done a lot of work with Spring, ColdSpring, and Spring.NET, it is hard to overstate the potential impact of AOP for Flash.
I also want to give a shout out to Maxim Porges, who spearheaded the effort to bring true bytecode generation to Flash with his Loom project. Without his effort this just wouldn't be happening.
For now, you can find full details on the new AOP features in the Swiz blog! As things get more stable, you can expect the Swiz documentation to incorporate this as well.
