How so?

How so? I wrote the following program:
import std.stdio;
void main() {
enum X = 2;
enum Y = 3;
enum Z = 4;
int[X][Y][Z] s;
int[X][Y][] d

Yet, there are no rows or columns because neither D nor C (nor C++) have
multip-dimensional arrays. They all have arrays where elements are

Ok, now I see the very sinister problem: It is a disaster to combine
static array lambda parameters with the

Probably

Fixed it by changing one of the lambdas to take by reference:
void toString(scope void delegate(in char[]) sink) const {

You can define an opIndex that takes any index type if the array is
defined by you:
import std.stdio;
import std.format;
struct indexedPair {
size_t x, y;
}
struct MyAr
Is it somehow possible to use a struct as a [multidimensional]
array index:
D
struct indexedPair
{
size_t x, y;
}
bool isMapPassable[100][100];
auto p = indexedPair(50, 50);
if(isMapPassable[p]) return true;
Probably not, but I'm curious.
