How to initialize static array member variable?

[Sebastian Schuberth]

Hi,

I'm still playing around with DMD 2.049 and my Vector struct. This
struct Vector(alias N,T)
{
    static immutable Vector X=Vector(1,0,0);

    this(T[N] v ...) {
        data=v;
    }

    T data[N];
};

alias Vector!(3,float) Vec3f;

gives

Error	1	Error: Slice operation this.data[] = cast(const(float[]))v 
cannot be evaluated at compile time		main.d	6

I also tried simply

struct Vector(alias N,T)
{
    static immutable Vector X=Vector(1,0,0);

    this(T x,T y,T z) {
        data[0]=x;
        data[1]=y;
        data[2]=z;
    }

    T data[N];
};

alias Vector!(3,float) Vec3f;

but that gives

Error	1	Error: Index assignment this.data[0u] = x is not yet supported 
in CTFE		main.d	6
Error	2	Error: Index assignment this.data[1u] = y is not yet supported 
in CTFE		main.d	7
Error	3	Error: Index assignment this.data[2u] = z is not yet supported 
in CTFE		main.d	8

Any other ideas how to introduce such an "X" constant?

Thanks.
