Argh, why is opSlice non-const? :-(  Please file a bug.

Not sure what you can do in the meantime... probably cast away const? Or
avoid using const for containers if you can. The last time I tried that,
I got stuck in a quagmire of partially-implemented const support with no
way out of the mess, and I decided that non-const is less painful to
work with. :-/
