default parameters question

[Stratboy]

Hi! Why can't I init my parameter with an object? Ex.

public static function createRect(opt = {x:0,y:0}){....

or

public static function createRect(opt:Object = new Object){....

It says:

1047: Parameter initializer unknown or is not a compile-time constant.

Because you're trying to instantiate an object within the parameters of a method. Your methods should be looking to receive an already existing object or some rudimentary values (number, strings etc). Someone may need to clarify this in case I am missing something.
