Hi,

I tried to do the following:
auto arr = new int[2][2];
arr[] = 1; // using array expressions
// The above gives - Error: cannot implicitly convert expression (1) of type
int  to const(int[2u][])

This was the first step to try out if array arithmetic that worked with single
dimensional arrays worked with multi-dimensional. I guess it does not.

The immediate utility of this would be to cleanly do matrix algebra. Any ideas
why powerful array expressions were not extended to multi dimensional arrays
as well?

I'm not sure this applies to your topic, but it gave me something to play with that may be related.

Static arrays are always laid out contiguously in memory. This appears to allow casting to a single dimensional array.

    auto a = new int[3][2];
    int[] test = cast(int[]) a;
    printf("%d\n", test.length); // Equals 6.
