These symbols cannot be externally linked directly, but it can be 
important for eg alias template parameters. (Everything needs to be 
manglable, even it can't be linked directly).

extern(C) {

void func() {
   // 'func' uses C name mangling

   void inner() {
     // 'inner' uses D name mangling.
     // So 'func.inner' is a hybrid.
   }

}
}

It's even possible to have extern(Windows) inner functions inside 
extern(C) functions!
