--- Comment #11 from Basile-z <b2.temp at gmx.com> ---
Very hypothetically, let's say that if "super" calls are supported in C++
classes then this means that maybe the super virtual table is stored somewhere.
If so then full dynamic casts would be possible.

Someone needs to study a bit more the ABI of extern(C++) classes in D.
Then maybe a dedicated dyncast() could be added to druntime.
