For example it is no problem in C++ to have
std::vector> vuf;
But how can this be expressed in D?
For example
Array!(Unique!int) ua;
doesn't compile because it requires this(this) which is obviously
disabled for "Unique".
Sorry for late reply -- but I got around to test a couple more
cases!

Sorry guys that I didn't express myself well. I also mixed some

int x = 3;
int y = 10;
int arr [x][y];
x,y are known at the compile time and arr is a static array. I
can't do that in D so what is the best way

since it always returns cast(void)0 regardless of the input.
But it cannot be that simple, so what am I missing?
Now notUsed has an unused parameter v.
