You use RTTI for dynamic casts, variadic functions, and the default 
implementation of toString. You could safely eliminate some fields from 
ClassInfo and TypeInfo, but you can't get rid of them entirely.

The best you can do is make TypeInfo entirely opaque (no fields) and 
only include the base class, interfaces, and name for ClassInfo.
