Title: Runtime Access to Type Information in C++

Abstract: The C++ language currently does not provide a mechanism for
an object to determine its type at runtime. We propose the
Dossier class as a standard interface for accessing type
information from within a C++ program. We have implemented a
tool called mkdossier that automatically generates type
information in a form that can be compiled and linked with an
application. In the prototype implementation, a class must
have a virtual function to access an object's dossier given
the object. We propose this access be provided implicitly by
the language through a predefined member in all classes.
