This is most definitely a dmd bug. Once you overload opCast, you can only cast
that type to the types that you've overloaded to cast to with opCast and the
_exact_ type that the variable already is. So, if it's S, you can cast to S but
not const S, shared S, or immutable S. If it's shared S, then you can cast to
shared S, but not S, shared S, or immutable S.

I don't know why you would think that this is not a dmd bug. Your original
example doesn't include BitArray at all.
