or something like this

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

byte[] data = getData();
ReferenceArray!(float[100][100]) matrix = data;
writeln(matrix[1][2]);
