Accessing array elements with a pointer-to-array

[Stephen Tashiro via Digitalmars-d-learn]

Can the elements of an array be accessed with a pointer using the 
usual indexing notation (e.g."[2][0]") for array elements? - or 
must we treat the elements associated with the pointer as 
1-dimensional list and use pointer arithmetic?

A more elementary question is why array index 2 is out-of-bounds 
in the following
code, which won't compile:
import std.stdio;

    void main()
    {
       ulong [3][2] static_array = [ [0,1,2],[3,4,5] ];
       ulong [][] dynamic_array;
       //ulong[][] *pointer;
       ulong *pointer;

       write(static_array);

       dynamic_array = new ulong[][](3,2);

       static_array[2][1] = 6;
       dynamic_array[2][1] = 6;

       pointer = static_array;
       writef("*pointer[2][1] = %d\n", *pointer[2][1]);

       pointer = dynamic_array;
       writef("*pointer[2][1] = %d\n", *pointer[2][1]);

    }
