Ah, thanks.

So I could probably re-write this as

```
     int* data = cast(int*)malloc(10 * int.sizeof);
     int[] slice = data[0 .. 10];
```

So maybe the issue is with being able to slice arbitrary 
pointers? I don't know...

It all seems tied in to the ability to conflate a malloc'ed slice 
with a GC'ed slice. If anything, I don't think it should be easy 
to do this.
