Initialising array variables using "As New" syntax.

I found myself writing this today:

```vb
Dim MyArray As New Integer(1024 - 1) {}
```

...and was surprised to see the compiler complain that too many arguments have been passed to `Sub Integer.New()`. Never in my life have I thought of calling a constructor on type `Integer`, so after some head scratching, I found the compiler wants me to write this instead:

```vb
Dim MyArray As Integer() = New Integer(1024 - 1) {}
```

Is there a reason the `As New` syntax is not supported for array variables?
