I beg to differ:


struct Vec { float x = 1, y = 5, z = 9; }

void main()
{
   {
     Vec v;
     assert(v.x == 1 && v.y == 5 && v.z == 9);
   }
   {
     auto v = new Vec();
     assert(v.x == 1 && v.y == 5 && v.z == 9);
   }
   {
     auto v = cast(Vec*)malloc(Vec.sizeof * 10)[0..10];
   }
   {
     auto v = new Vec[10];
     v[] = Vec(0,0,0);
     assert(v[1].x == 0 && v[1].y == 0 && v[1].z == 0);
   }
}
