There's a much more fundamental problem with it: C++ doesn't support it! 
You can't compile a file with MSVC and link it to something compiled 
with g++.
Look up my CodeProject article on member function pointers -- every 
vendor has their own API, and virtually none of them are documented.

On Windows, extern(C++) means extern(DMC++), but for me, the only thing 
I'd want to link to is MSVC. Much more useful would be, as Brad says, to 
provide a way of specifying the name mangling. If we could do that, we'd 
be more compatible with C++ than C++ is to itself.
