Maybe I'm the only one, but I think double*[] is hideous, and I'd 
sure hate for someone not used to D to see it. Alias is your 
friend. I think this is much nicer:

void main() {
     alias double* DoublePtr;
     DoublePtr[] arr;
     auto v = [1.0, 2.0, 3.0];
     auto w = [4.0, 5.0, 6.0];
     arr ~= [v.ptr, w.ptr];
     writeln(arr);
}
