I'm actually not sure if that [DIR] is an associative array or 
DIR's base type or a static array of DIR's size.

I *think* it is an assoc array... let's test it using the `in` 
operator:

         auto a = DIR.UP in bmps;

That compiled. So this must be an associative array!


Try this instead:

BITMAP*[2][DIR.max] bmps;


That's a static array of directions and I think that's what you 
intended and the other things should work as you want too with 
this.
