This can still be done. If you have the compile-time type you can always
forcefully generate the run time info (I would expect such a feature
when RTTI is fully developed).
The thing is that you may not have access to the compile-time type,
i.e. :
class Base {}
class Sub : Base {}
Base sub = new Sub;
Now the compile-time information specific for Sub is gone when
accessing "sub".
I have this problem with my serialization library. To workaround this
the user have to register the compile-time type with the serializer to
be able to (de)serialize via base class references.
Well, .NET requires you to put an attribute on a class to allow it to be
serializable. And that doesn't seem to get in the way of .NET code that
uses serialization.

If I can make it work without specifying an attribute on a class why
shouldn't I. One thing less to think about. It's just in this special
case the type needs to registered with the serializer.
