Below is a sample code. I could not figure out why i is string and not Number/int.

```auto

//The code below does not work
var numArray:Array = [1,2,3,4];

for(var i:int in numArray){
	trace(i);
	trace(numArray*);
}

```

```auto

//The code below works
var numArray:Array = [1,2,3,4];

for(var i:String in numArray){
	trace(i);
	trace(numArray*);
}

```
