Consider the following code to keep track of rectangle positions

providing get/set properties for one-based positions but only get

It doesn't.
T[] a;
just works. it is an array of length 0.
Consider initializing a dictionary or associative array :
T[U] AA;
For example :
double [int] AA;
This will be dynamic in size.
Now consider initializing a dynamic array :
T[] A = new T[] (0);
or
U[][] B = new U [][] (0,0);
This will also be dynamic in size.

Hi,
Consider Allocators, e.g.:

That's right. I typically don't use Dub when I'm calling D
functions from R. It's the only way you can use a Dub package
like Mir, though, so that's why you might want it to generate a
