Subject RE: To AS4 or not
Date Sat, 20 Oct 2012 21:10:14 GMT
I cannot wait to see the specs of AS4, and love to help out porting Flex
framework from AS3 to AS4.  What would be interesting is to see how to
maintain the parity between the two versions, but a good technology is worth
the pain to keep it up to date.

work for us and it isn't trivial. ActionScript is more complex than MXML.
