Sure, I didn't mean to push, always mind the DoD! :-) Another goal to get something a bit more complex working could be FlexUnit. For Jangaroo, we use an older version<https://github.com/CoreMedia/jangaroo-libs/tree/jangaroo-3/joounit>(I think it is called 0.9) that works without test annotations and uses only very few Flash/Flex APIs. FlexUnit has over 60 self-tests, so if we could get it to run and see those tests green (like it is the case with the code produced by Jangaroo 3), we'd get even more confidence/proof that this actually works.
Just an idea... -Frank-
