I think you're right that you can't find out at runtime that 'bar' was typed as IBitmapDrawable. But using IBitmapDrawable as a type annotation does ensure that it gets compiled in unless you deliberately exclude it.

Example: function foo():void { var bar:IBitmapDrawable = new BitmapData(); } you can only know what the type of the value is ( BitmapData ) the type of the "bar" variable (IBitmapDrawable) may not even exist in the compiled code - there's no need for it to exist anyway.
