multidim array with enum

[Chris Katko via Digitalmars-d-learn]

I'm having difficulty figuring out exactly what signature D is 
expecting.

````D
enum DIR
        {
                UP = 0,
                DOWN,
                LEFT,
                RIGHT,  
                UPLEFT,
                UPRIGHT,
                DOWNRIGHT,
                DOWNLEFT,
        }
BITMAP*[2][DIR] bmps;

// ...

bmps[DIR.UP][0] = nope.
bmps[DIR.UP][0] = new BITMAP *; // nope
bmps[DIR.UP][0] = new BITMAP; // nope
bmps[DIR.UP] = new BITMAP*[2]; // compiles. runtime range 
violation.

````

I swear this all worked fine when it was just:
````D
bmps[DIR] bmps;
````
