> Now, how do you apply it to particular dimensions of some larger arrays?

What exactly is the complaint here? If I write a function on a 2x2 array, there's no way to apply it to tiles in a 3x2x2 array? But there is - take a slice and squeeze. What's the issue?

Edit: if the issue is some weird version of "why can't I apply my function to an arbitrary set of indices" (like the 0,1 in a 2x2x2 array) I'm at a loss for words (because that's a completely different shape - indeed it's the entire array).
