Also as I say in the wiki page, and I hope what I said is true, your second example should fail to compile in the swf10 runtime. The Flex compiler should notice that you are calling a non-existent super method at compile time, and complain.
There isn't a compile time error; just a runtime error. ERROR @c3.lzx≈10: ReferenceError: Error #1070 drawmixin1.draw init myclass.draw init The HTML5 compile has a better error message: ERROR: super.draw is undefined in draw drawmixin2.draw init drawmixin1.draw init myclass.draw init
