is this the correct way to set a dynamic 2D array?

int[][] dynamic;

dynamic.length = width;

for (int i = 0; i < dynamic.length; i++)
    dynamic[i].length = height;

Just seems a bit weird.

Currently, yes. Though it could also be written as ...

 int[][] dynamic;
 
 dynamic.length = width;
 
 foreach (inout int[] x; dynamic)
     x.length = height;

can't you just say this?
dynamic[].length = height;

No. You get this message ...

 slice expression dynamic[] is not a modifiable lvalue

Isn't this something that would be possible with array vectorization?

I'd really love this syntax..
