I think that's pretty neat, but it only moves, rather than removes the  
duplication, although I can see that it's easier to verify in one place  
like that. (I also needed to add an implementation to the cpp file to  
provide storage for foo::_theInfo to get it to link under VC9.)

It also generates code-to-generate-data rather than data, which was  
something I was keen to avoid as much as possible. That said, if you  
remove the virtual base then the compiler generates pretty good code. That  
would allow you to separate the "find what type" code (one virtual call)  
 from the "interrogate type data" (no virtual calls) code.

Cheers,
