Swiz framework for Flex

In a discussion thread at the LinkedIn Adobe Flex Developers Group, about what framework to use for developing large Flex applications someone mentioned Swiz:

- an Inversion of Control framework so you don't end app with any singleton references in your project code but you can wire your objects together using metadata annotation in your classes

- no repetitive folder layouts, and no boilerplate code on your development

As I am currently doing some heavy refactoring of a prototype project in order to take the application to the next level, the above statements really seems promising, and it would have been great if I could have these benefits.
