What's the point of that? You still can't use a dynamic cast if it is possible 
that a plugin/part is loaded with RTLD_LOCAL.

I think it is a good idea to promote the use of namespaces. If we start now 
then maybe by the time of KDE 4.0 we can decide whether we can start loading 
all libs with RTLD_GLOBAL. Till that time qt_cast is the way to go IMO.
