you can make a thin wrapper that will work as a reference-type static array

struct ReferenceArray!(ElementType, int columns, int rows)
{
  ElementType[columns][rows]* back;
  this(byte[] data)
  {
    assert(data.length==ElementType.sizeof*columns*rows);
    back = cast(ElementType[columns][rows]*)data.ptr;
  }
  //will it be inlined?
  ElementType opIndex(int column, int row)
  {
    return (*back)[row][column];
  }
}
