Thanks. I might go for a design like this:

```
struct View(T){
   T* data;
   long[2][] ranges;
}
```
The ranges are were the slices are stored and T* (maybe even 
immutable(T*)) is a pointer is to the start of the original 
array. I'll use an opIndex that calculates the correct index in 
the original array to obtain the right data.
