I have a stupid question. I got this variable:

```auto

    var type:int;

```

and this function:

```auto

    private function test(type:int):void {
    }

```

when i call the function and throw in my variable type

```auto

    test(type));

```

is there a possibility that the compiler gets confused because my variable has the same name like the functions’s parameter (type = type)? i’m not certain about this topic. Normally I’d write my function’s parameter like this (if such a case occurs):

```auto

    private function test(_type:int):void

```

just to make sure the names do not exactly match (well I hope you know what I mean).
