Sure, I'd be interested to hear any improvements. Like I said in my 
answer, I'm still learning D so I'm sure there's many issues. For 
example, I made no attempt for const-correctness or anything like that 
(mostly for simplicity).

In particular, I'd be interested in knowing if there's a better way to 
write opDispatch i.e. a way that doesn't use that ugly mixin.
