During the discussion of the Fx prefix thing I was reminded when I was creating my own classes of the same name. For example, I think I was extending button and didn't want to change the name to anything else besides "button" so I had:
public class Button extends mx.controls.Button Then in my application code hinting would always throw a disambiguity error. So I was trying to remember if there was a way to alias my Button from the mx Button and the not have the compiler throw errors or make me write out the full class names each time (to get around the error).
