If I use array:

extern(C++) {
void getInts(core.stdcpp.array.array!(int, 10) vec) {
foreach (int i; 0 .. 10) {
vec.at(i) = i;
}
}
}

```
#include
using namespace std;
void getInts(array* vector);

Because of this the offsets are wrong. So you wouldn't be

Hi,
I'm following this example:

My recommendation is to use a free function or a `static`

Hi, below is an example of DI-dependency injection with 3

characters, you will not get the "no property `deliver` for
