Is it possible to define a generic type Vector in Actionsctipt 3?

Hi i need to make a VectorIterator, so i need to accept a Vector with any type. I am currently trying to define the type as * like so:

var collection:Vector.<*> = new Vector<*>()

But the compiler is complaining that the type "is not a compile time constant". i know a bug exists with the Vector class where the error reporting, reports the wrong type as missing, for example:

var collection:Vector.<Sprite> = new Vector.<Sprite>()

if Sprite was not imported, the compiler would complain that it cannot find the Vector class. I wonder if this is related?
