A Multi-dimensional array implementation would be cool, similar to the one in C#, rather than using Java's jagged arrays.
So you could make a 2x4 array arr, and because we know the width and height are fixed to 2 and 4, we can make it a 1D array of length 8.

On JVM, arrays are references, so, unfortunately, this is valid (Java): int[][] crap = { {1, 2}, {3, 4, 5}, null };

Sorry for the late reply. I understand how 2D arrays in Java work. But what I'm suggesting is a feature that, if specified in a 2D array (ex syntax: Array2D<String>(2, 4) which is stored internally as a single array of length 8, but from the outside is accessed as arr2d[1, 3] //for last element

Is it okay to bump this thread? I feel like this would be extremely useful. Probably better for #stdlib though

You can write your own wrapper around arrays. This is not the case for #stdlib, but for a library.
