It really should be stopped at compile time. There's not really a good reason
to allow it. As much as it first looks like mixing A[] and B[] when B : A
should work, it's a _really_ bad idea. Just because a container holds a type
which is the base type of another type does not mean that a container which
holds the derived type should be assignable/castable/convertable to one which
holds the base type.
Really, the only question is whether you can get away with it with some form of
const, and I believe that the consensus on it in the newsgroup last time that
this was discussed was that you couldn't. I'd have to go digging through the
archives though to find the exact thread.
This can and should be disallowed at compile time. It's a definite bug. It just
hasn't been fixed yet.
