--- Comment #12 from Basile-z <b2.t...@gmx.com> --- (In reply to Basile-z from comment #11) > 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. > this supplemental comment was BS. Obviously `super` does not use the vtable. > 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. --
