This is definitely something I have always wanted to see in AS3.
If this were to be implemented, one thing that should be allowed is
something like this:
```as3
var fun:Function.<(ev:Event):void> = function(ev:Object):void {};
```
To be clear, Event is a subclass of Object, so that function should be
allowed for the same reason why you can assign an `Event` instance to a
variable of type `Object`.
```as3
var obj:Object = new Event();
```
With return types, there's a similar situation, but instead of superclasses,
subclasses would be allowed.
```
var fun:Function.<():Object> = function():Event {}
```
