If you want to use this syntax with images, DMagick's ImageView might

I like it :)
From what I can see it provides exactly what i'm talking about for 2D.
I haven't looked at the implementation in detail, but do you think that
such an approach could be scaled up to arbitrary N-dimensional arrays?
Yes and no. Basically, like an array, an ImageView is a thick pointer and
as the dimensions increase the pointer gets thicker by 1-2 words a
dimension. And each indexing or slicing operation has to create a
temporary with this framework, which leads to stack churn as the
dimensions get large. An another syntax that can be used until we get
true, multi-dimensional slicing is to use opIndex with int[2] arguments,
i.e: view[[4,40],[5,50]] = new Color("red");
