Since we do not have attributes for enums, I use _ in front of
the names for meta values.
I need to get the non-meta values for the enum so I can iterate
over it and use it properly.
enum myEnum
{
_Meta1 = 0,
A,B,C,
_Meta3 = 43,
D = 3,

In short, you are right, `int[4][4][]` is a dynamic array of
`int[4][4]`. In t
I was trying to figure out why calling an object's function from
a wndProc that modified the object's state didn't actually change
anything. Wrapping the GetWindowLongPtr in a cast(void*) seems to
make it work. What am I missing about this? I though that object
references were really just point

I'm a bit confused by how D does arrays.
I would like to create a array of matrices but I do not seem to
get the correct behavior:
int[][4][4] matrix_history;
What I would like is to have a 4x4 matrix and have a history of
it. Just n 4x4 matrices but each matrix is a fixed size but there

When you ensure pointers point to existing data, you can
