Hmm Thomas, Sounds very interesting. I've been doing a lot of work writing lexers for Saffron so I could be of assistance if I find the time in the future. But I have some questions. Are you planning to do a full compiler that supports embedded images, fonts, sound, etc. or just an Actionscript one. Also what VM are you planning to target AVM1( Flash 8 and lower) or AVM2(Flash 9). I think a Flash 9 is needed. While Actionscript 3 is a great improvement it's a far cry from far more mature and professional languages like Objective C, C# or even Java. There are a lots and LOTS of things in Actionscript 3 that need to be added in order to make it into a mature language and I think that an open source AVM2 compiler would be great. This way the community could decided what features to add in and not some folks somewhere locked up in some ivory tower consortium!
