If you have const data referencing mutable data, then yes, you can cast

This is not guaranteed to work. I guess the only related thing that is
safe to do is casting away const, but then not modifying the memory.
For what practical reason would that be the case? I know that the spec
states "undefined behavior", but AFAICS, there is neither an existing,
nor a theoretical reason, why this should fail:
int* i = new int;
const(int)* j = i;
int* k = cast(int*)j;
*k = 0;
Anyway this is going pretty much off topic...
