Thanks for the comments. The all-caps enums is just habit. I 
don't get any warnings using the dmd -w switch, I take it you 
mean use int[size][size] var instead?

Regarding the immutable loop variable, I've conditioned myself 
never to interfere with loop control values - it gives me the 
same bad feeling as goto/continue (and to a lesser extent 
'break').
