I really don’t like the x as an operator either, because I use x for so many other things in my code. 

My typical use case for contiguous variables would be images, e.g:

struct RGBAPixel {
	var red: Int8
	var green:Int8
	var blue:Int8
	var alpha:Int8

let myImage : RGBAPixel[512 * 515] = someCFunctionThatReturnsABitmap() as! RGBAPixel[]

I recently needed to do this kind of thing in a Swift tool that converted images into CIColorCubes, and it was nightmarish.   I almost reverted to C to get it done.

On a related note, I’d really love to have a way to declare multi-dimensional arrays and be able to name the axes.
