C++ exception mechanism uses C++ type_info objects. We can inherit

exceptions, we should implement and support another one
non-standartized feature: type_info. BTW it allows to do dynamic_cast
over C++ classes in D, but I think, nobody approve this suggestion,
because it can be hard).
Objective-C can do it somehow. If they can do it I'm sure we can as well.

If someone from D commanders bless me, I can start to exploring and
implementing std::type_info for D classes. If we made it, we will
implement 50% of C++ exception handling.
Would that be for throwing exceptions from D into C++? I think we can
postpone that for now. -- Andrei
