If I have say a dozen classes, that may or may not be called at runtime, and that all have a common function; is there an advantage to creating a separate class with just this common function in it and then having it mixin at runtime ?
I am wondering would this allow me to reduce the size of each class and thereby the swf file size? I figure this must be wrong else why would we ever extend anything when we could just mixin the functionality we want at runtime?
